What is the difference between qualitative and quantitative data analysis?
A qualitative approach is more on the research side and helps in exploratory analysis tasks. However, to study data and get actionable insight from it, one has to choose quantitative data analysis since it provides us meaningful results using complex statistical concepts and tools. OUTLINE: What is Data Visualization?
What is archival data?
What are archival data? Archival data refer to information that already exists in someone else’s files. Originally generated for reporting or research purposes, it’s often kept because of legal requirements, for reference, or as an internal record.
What are the advantages and disadvantages of quantitative data?
A big advantage of quantitative data is that it’s relatively quick and easy to collect, meaning you can work with large samples. At the same time, quantitative data is objective; it’s less susceptible to bias than qualitative data, which makes it easier to draw reliable and generalizable conclusions.
Can archival data be used to evaluate the effectiveness of programs?
It may be possible in that case to find archival data that will allow you to determine the program’s effectiveness in terms of process, outcomes, or both. Although you’ll probably collect information on the participants in the program you’re evaluating, there are a number of ways you might use archival data:

When should you collect and use archival data?
When it’s available . This is the key question. If you know the data exist and you can get access, use it. If the data doesn’t exist, if finding it would take more time and effort than it’s worth, or if you have no access to it, then it’s not possible.
Where can archived data be found?
Archival data can exist almost anywhere that information is collected.
Why do government agencies keep archival records?
Most government agencies and departments, community-based health and human service providers, advocacy organizations, universities, and many other entities keep archival records of information. You may be able to use these as part of the data for your evaluation, saving time and trouble. Especially for small organizations with limited resources, the use of archival data can make it possible to produce an evaluation that provides the information needed to accurately assess a program’s effectiveness and make the changes necessary to improve it.
What is section 1 of the evaluative process?
Section 1. Choosing Questions and Planning the Evaluation
Why is data kept?
In general, because it’s the result of completed activities, it’s not subject to change and is therefore sometimes known as fixed data.
Is census data used in evaluation?
As explained above, much of the data you’re likely to use for evaluation purposes will probably be more focused than data you’d use for an assessment of the level of a problem. Evaluation information would be more likely than assessment data to come in the form of study results, for example, than as narrative history or original documents. There’s a good deal of overlap: census data, for instance, could be used in both assessment and evaluation. In general, however, the possibilities below would refer to the types of data available, including information for a specific population or geographic area on:
What is the difference between qualitative and quantitative data?
Let’s summarize the key differences before exploring each aspect in more detail: Quantitative data is countable or measurable, relating to numbers. Qualitative data is descriptive, relating to language.
How is qualitative data collected?
Qualitative data is collected by interviewing and observing. Quantitative data is analyzed using statistical analysis, while qualitative data is analyzed by grouping it in terms of meaningful categories or themes.
Why do we use qualitative data?
Researchers will often turn to qualitative data to answer “Why?” or “How?” questions. For example, if your quantitative data tells you that a certain website visitor abandoned their shopping cart three times in one week, you’d probably want to investigate why—and this might involve collecting some form of qualitative data from the user. Perhaps you want to know how a user feels about a particular product; again, qualitative data can provide such insights. In this case, you’re not just looking at numbers; you’re asking the user to tell you, using language, why they did something or how they feel.
Why is quantitative data important?
A big advantage of quantitative data is that it’s relatively quick and easy to collect, meaning you can work with large samples. At the same time, quantitative data is objective; it’s less susceptible to bias than qualitative data, which makes it easier to draw reliable and generalizable conclusions.
What are the two types of data?
If you’re considering a career in data—or in any kind of research field, like psychology—you’ll need to get to grips with two types of data: Quantitative and qualitative. Quantitative data is anything that can be counted or measured; it refers to numerical data. Qualitative data is descriptive, referring to things that can be observed ...
How to analyze quantitative data?
How you analyze your quantitative data depends on the kind of data you’ve gathered and the insights you want to uncover. Statistical analysis can be used to identify trends in the data, to establish if there’s any kind of relationship between a set of variables (e.g. does social media spend correlate with sales), to calculate probability in order to accurately predict future outcomes, to understand how the data is distributed—and much, much more.
What is continuous quantitative data?
Continuous quantitative data can be placed on a continuum and infinitely broken down into smaller units. It can take any value; for example, a piece of string can be 20.4cm in length, or the room temperature can be 30.8 degrees.
Abstract
In this article some of the conceptual and technical issues relating to data archiving in relation to documentation, research, and teaching are discussed.
References (0)
This chapter discusses one particular and often overlooked aspect of survey quality – the consistency between different sources of documentation containing metadata that define variables and their values in questionnaires and codebooks, and between the numerical data records. It proposes a typology of processing errors in survey documentation.
Qualitative and Quantitative Data Analysis: Definitions & Examples
Qualitative data analysis is the process of data analysis employed when the data at hand is characteristic. Such data cannot be represented in numerical form and hence is also sometimes called meaningless since we can give it any value we want, relatively.
Is Data Analysis Qualitative or Quantitative? The rationale
Data analysis is nothing but a way to study data to its depths to extract underlying information such as the hidden trends or patterns.
Data Analysis Pipeline
If we look at the process of data analysis from a broad perspective, it consists of two core activities: data preparation and then finally, data analysis. Let’s see what each of them consists of.
Writing Your Dissertation
For new and aspiring doctoral students, the idea of writing a dissertation of several hundred pages can be overwhelming. Fortunately, it’s possible to break the process down into concrete steps that are easier to manage. Long before you dive into quantitative data collection methods, you’ll need to complete the following steps:
What Is Quantitative Data?
All quantitative data are expressed in numeric form. Quantitative research strives to answer questions such as “How much?” “How often?” and “How many?”.
Quantitative Data Collection Methods
Students can choose from several primary methods of collecting quantitative data to shape their dissertation. This includes the following methods:
What are qualitative methods?
We define “qualitative methods” broadly, including interviews, participant observation, ethnographic mapping, the recording of oral histories, focus groups, and historical source analysis, as well as some aspects of surveys (particularly less structured protocols) and experiments (e.g., debriefing after experiments).
What is micro-historical analysis?
Micro-historical Analysis in Social Science Research (or Historical and Archival Methods) analyzes pairs of ‘classic’ and contemporary research on some of the most important topics across social science disciplines, prioritizing a ‘hands-on’ approach based on discussion of how the archive came to be created, salient design choices, how to conduct archival research, and replication of the results of papers that use historical evidence. Recent students have consulted archives at Yale, and other private and government archives in the USA, and across the world, with topics as varied as race and the criminal justice system in the USA, the 1971 India-Pakistan war, ethnic politics in the Balkans, gender and politics in Ethiopia, and great power politics as seen through the various private archives collected at Yale, such as the Kissinger and Stimson archives. Other student projects include GIS-based research that combine historical with contemporary data, text-analysis that uses archival and historical parliamentary sources, the formulation of research projects that leverage historical natural experiments.
What is mixed methods research?
Mixed Methods Research bridges training in quantitative and qualitative methods. The course is intended as an overview for creating and critiquing sophisticated research designs using both quantitative and qualitative methodologies, data, and analyses. The course begins with the logics and assumptions underpinning qualitative, quantitative, and mixed methods research, and then moves on to analyzing the strengths and weaknesses of specific combinations of quantitative tests, case studies, and narrative and interpretive work. The final assignment builds on the course material to produce a mixed method research design proposal, and is ideal for students in the prospectus writing stage of their dissertation.
What is archival data?
Archival data. Archival data, or backups, can take many forms. External hard drives, DVDs, and backup tapes are just a few examples. Acquisition of archival data can range from simple to extremely complex. The type and age of the backup media are major factors in determining the complexity of the process. Backup tapes can present some very big ...
Why is archival data off site?
Once we decide to relocate the data, we realize that even though relocating archival data to an off-site location reduces one risk (loss of data through local disaster), it introduces another risk (unauthorized access) because the data is transported and stored elsewhere. If the data are encrypted before transit, we can mitigate the new risk, but now we need to have a way of decrypting the data remotely, in case we lose all our systems locally. If we archived data using a tape backup archival system, such as VERITAS, we need to acquire a second system for the second set of archival data for our alternate location. Naturally, we need to transport the encryption key, so we can decrypt the data later if needed—we can’t send the key during transit of the data, in case the data get stolen along the way.
Why is batch analytics important?
Batch, real-time, and streaming data-analytics are important in the context of analyzing data collected on smart facilities. As discussed earlier, batch analytics is performed on stored archival data, whereas real-time analytics is needed when an event (eg, a storm) occurs, requiring the analysis of the effect of the event on the smart facility in real time. MapReduce and MapReduce with deadlines can be used in these two situations respectively. Streaming data analytics is required when streams of sensor data need to be analyzed continuously for determining the health of the system, for example. Parallel-processing frameworks such as Storm [38] have been developed for performing streaming data-analytics. Resource management for achieving effective streaming data-analytics has started receiving attention from researchers recently. Existing work includes using parallel processing to provide Quality of Service (QoS) guarantees for stream processing, described in [39]. A reactive scaling strategy to enforce latency constraints on the computation performed on a Stream Processing Engine is presented in [40]. No permanent static provisioning is assumed, and the technique can effectively handle varying workloads. Resource management for systems supporting streaming analytics is an important problem and needs further investigation.
Why is data analytics important in smart facilities?
Using batch-data-analytics techniques on archived data is to be performed, for example, to determine the next maintenance cycle, whereas real-time data analytics that concerns the processing of sensor data in real time may be important for performing real-time control of the facility or for handling emergencies. MapReduce is a well-known technique [33] that is used for performing data analytics on large volumes of data that are typical of smart facilities. The basic idea behind MapReduce is briefly explained.
What is empirical research?
Introduction. Social scientists engaged in empirical research—that is, research seeking to make claims or inferences based on observations of the real world —undertake an enormous range of activities. Some investigators collect information from primary sources; others rely primarily on secondary archival data.
What is the most problematic type of data?
Archival data typically provide more adequate documentation than official statistics taken directly from agencies. The most problematic are official records in which abbreviations or shorthand is used in the records. In the latter instance, it is necessary to discuss with records managers what each of the symbols mean.
What are the factors that determine the complexity of a backup?
The type and age of the backup media are major factors in determining the complexity of the process. Backup tapes can present some very big challenges, especially if they were made with software or hardware that is no longer in production. Tapes are created using specific pieces of hardware and software.
