a)Differentiate between descriptive and inferential statistics. descriptive Statistics Descriptive statistics embroils statistical procedures that we use to make out the commonwealth we are studying. The entropy could be collected from either a take in or a population, but the results help us fig out and break data. Descriptive statistics stinker only be employ to divulge the group that is being studying. That is, the results can non be reason out to any big group. Descriptive statistics are useful and serviceable 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 alone parents, entirely told women, all victims, and so on Frequency distributions, measures of central aspiration (mean, median, and mode), and graphs like pie charts and bar charts that describe the data are all examples of descriptive statistics. il lative Statistics Inferential 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 popularize 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 shout this issue of generalization, we have tests of importation. A Chi-square or T-test, for example, can ramify us the luck that the results of our analysis on the sample are representative of t he population that the sample represents. In! other words, 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 requisite to get a broad(a) essay, order it on our website: OrderCustomPaper.com
