Research Methods

a)Differentiate between descriptive and inferential statistics. descriptive Statistics Descriptive statistics take ons statistical procedures that we use to make out the commonwealth we argon studying. The info could be collected from either a take in or a population, but the results help us contrive and break data. Descriptive statistics give the gate only be utilize to divulge the group that is being studying. That is, the results can non be extrapolate to any big group. Descriptive statistics are useful and operable 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 either parents, each(prenominal) women, both victims, and so on Frequency distributions, measures of central tilt (mean, median, and mode), and graphs like pie charts and bar charts that describe the data are all examples of descriptive statistics. illative 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 vulgarize 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 dole out this issue of generalization, we have tests of consequence. A Chi-square or T-test, for example, can regularize us the luck that the results of our analysis on the sample are represent ative of the population that the sample repr! esents. 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 take to get a broad(a) essay, order it on our website: OrderCustomPaper.com
