a)Differentiate between descriptive and inferential statistics. descriptive Statistics Descriptive statistics holds statistical procedures that we use to make out the commonwealth we ar studying. The information could be collected from either a take in or a population, but the results help us bring up and break data. Descriptive statistics preserve only be use to divulge the group that is being studying. That is, the results can non be infer to any large group. Descriptive statistics are useful and useful if you do not need to extend your results to any larger group. However, much of kindly sciences tend to include studies that give us universal truths nearly segments of the population, such as only parents, each women, only victims, and so on Frequency distributions, measures of central list (mean, median, and mode), and graphs like pie charts and bar charts that describe the data are all examples of descriptive statistics. illative Statistics Infer ential statistics is concerned with making predictions or inferences about a population from observations and analyses of a take in. That is, we can take the results of an compend using a sample and can generalize it to the larger population that the sample represents.

In order to do this, however, it is imperative that the sample is exemplar of the group to which it is being generalized. To name and address this issue of generalization, we have tests of implication. A Chi-square or T-test, for example, can severalise us the luck that the results of our analysis on the sample are representative of the popula tion that the sample represents. In other wo! rds, these tests of significance tell us the probability that the results of the analysis could have occurred by chance when there is no relationship at all between the variables we studied in the population we studied. Examples of inferential statistics include linear regression analyses, logistical regression analyses, correlation analyses, structural...If you pauperization to get a broad(a) essay, order it on our website: OrderCustomPaper.com
