Types of Statistics.
1.Descriptive statistics are used to describe and summarize data. Their objective is to communicate results, without generalizing beyond the sample ,to any population .
Some ways in which results are communicated are through
a. measures of central tendency (mean, median ,and mode)
b. measures of dispersion
2. Inferential statistics are used to apply information from the sample to a larger population.

 For example, you might stand in a mall and ask a sample of 100 people if they like shopping at Sears. You could make a bar chart of yes or no answers (that would be descriptive statistics) or you could use your research (and inferential statistics) to reason that around 75-80% of the population (all shoppers in all malls) like shopping at Sears.
