Why is descriptive analysis important?
The descriptive analysis is fruitful for the researchers to represent the data easily and develop an in-depth analysis and critical evaluation. The frequency and variability of the data can be analysed efficiently to conduct research successfully. Measures like segregation, discrimination, and inequality are also possible through a descriptive analysis where SPSS tool, tables and graphs are suitable to represent the quantitative data analysis and it also provides a scope to develop interlink quantitative and qualitative data for further critical evaluation. Hereby, cross-tabulation, graphs, median and mean analysis are effective to consider historical data and analyse the factors in the data set. different exposure of the data can also be possible, where the researchers try to utilise excel and SPSS tools for data representation and conducting in-depth critical analysis in order to have effective regression, central tendency and variance for further interpretation of the quantitative data.

What are the measures of variability?
Measures of variability give you a sense of how spread out the response values are. The range, standard deviation and variance each reflect different aspects of spread.
What is standard deviation?
The standard deviation ( s) is the average amount of variability in your dataset. It tells you, on average, how far each score lies from the mean. The larger the standard deviation, the more variable the data set is.

What are some examples of prescriptive analytics?
An oft-cited example of prescriptive analytics in action is maps and traffic apps. When figuring out the best way to get you from A to B, Google Maps will consider all the possible modes of transport (e.g. bus, walking, or driving), the current traffic conditions and possible roadworks in order to calculate the best route. In much the same way, prescriptive models are used to calculate all the possible “routes” a company might take to reach their goals in order to determine the best possible option. Knowing what actions to take for the best chances of success is a major advantage for any type of organization, so it’s no wonder that prescriptive analytics has a huge role to play in business.
How do predictive models work?
Predictive models use the relationship between a set of variables to make predictions; for example, you might use the correlation between seasonality and sales figures to predict when sales are likely to drop. If your predictive model tells you that sales are likely to go down in summer, you might use this information to come up with a summer-related promotional campaign, or to decrease expenditure elsewhere to make up for the seasonal dip. Perhaps you own a restaurant and want to predict how many takeaway orders you’re likely to get on a typical Saturday night. Based on what your predictive model tells you, you might decide to get an extra delivery driver on hand.
