What are the basic topics of statistics?
All of the major topics of an introductory level statistics course for social science are covered. Background areas include levels of measurement and research design basics. Descriptive statistics include all major measures of central tendency and dispersion/variation. Building blocks for inferential statistics include sampling distributions, the standard normal curve (z scores), and hypothesis testing sections. Inferential statistics include how to calculate confidence intervals, as well as conduct tests of one-sample tests of the population mean (Z- and t-tests), two-sample tests of the difference in population means (Z- and t-tests), chi square test of independence, correlation, and regression. Doesn’t include full probability distribution tables (e.g., t or Z), but those can be easily found online in many places.

Introduction to Probability and Statistics
Observing Outcomes of Events
- Some data, such as air pollution levels and bird migration paths, are observed through real-life situations. 1. Air pollution levels are observed by taking random air samples. 2. A bird migration path is traced by tagging a sample population of birds with identification numbers.
Conducting Surveys
- We usually conduct surveys to gather personal data and public opinion by requesting sample populations of target groups to complete a questionnaire. The survey may be performed through face-to-face interviews, telephone interviews, postal surveys, or Internet surveys. 1. The United States Census is a \(100\% \) population survey that is conducted once in \(10\) years 2. Custo…
Reading Statistical Publications
- Some data such as economic conditions and a country’s population are obtained by conducting large-scale surveys that individuals or small companies cannot do. We can receive these types of data from official statistics published by government organisations. The United Nations Statistical Yearbook contains a wide range of international economic, social, and environmental data.
Important Terms Related to Statistics
- Some of the important terms related to statistics are as follows: 1. Primary Data: The information collectedby the collector himself with a definite purpose in their mind is called primary data. 2. Secondary Data: The information gathered from a source already stored is called secondary data. 3. Raw Data: The numerical data recorded in its original form as collected by the investigator or r…
Tabulation of Raw Data
- Suppose there are \(32\) students in Class \({\rm{IX}}\) in a school and in an examination, out of \(50\) marks, the marks obtained by them are as follows: \(39,44,25,11,21,25,44,25,7,40,43,44,49,14,11,14,25,28,28,39,44,37,21,40,\) \(43,3,37,25,25,21,37,38\) The data in this form is the raw (or ungrouped or unclassified) data. H…
mean, Median and Mode of Ungrouped Data
- The mean or arithmetic average of a number of observations is the sum of the values of all the observations divided by the total number of observations. Mean \( = \frac{{{x_1} + {x_2} + {x_3} + \ldots {x_n}}}{n} = \frac{{\sum {{x_i}} }}{n},\) where \(\sum {{x_i}} = {x_{1 + }}{x_{2 + }}{x_{3 + }}{x_{4 + }} \ldots \ldots {x_n}.\) Thus, mean \( = \frac{{{\rm{ Sum}}\,{\rm{of}}\,{\rm{all}}\,{\rm{observati…
grouped Or Classified Data
- Consider the class intervals \(1-5, 6-10, 11-15,….\) And the other class interval as \(1-10, 10-20, 20-30, 30-40,….\) In the class interval \(1-5, 1\) is the lower limit, and \(5\) is the upper limit. If \(x\) is a member of this class, then \(1≤x≤5.\) Similarly, \(6\) is the lower limit, and \(10\) is the upper limit of class \(6-10.\) In this example, the classes are not overlapping but discontinuous. Such …
Converting Discrete Distribution to Continuous Distribution
- If we measure height, weight and time, there may be fractions of a meter, kilogram and hour respectively, therefore we need continuous distribution. To convert discrete classes into continuous classes, we require some adjustments. Adjustment factor\( = \frac{{{\rm{ lower}}\,{\rm{limit}}\,{\rm{of}}\,{\rm{one}}\,{\rm{class – upper}}\,{\rm{limit}}\,{\rm{of}}\,{\rm{pre…
