What is heteroscadacity?
In regression analysis , heteroscedasticity means a situation in which the variance of the dependent variable varies across the data. Heteroscedasticity complicates analysis because many methods in regression analysis are based on an assumption of equal variance.

How do you do inferential statistics?
Inferential statistics is the practice of sampling large sets of data (usually at random) to gain information about the population as a whole. Sampling is used because measuring everything in the population can consume too many resources (time, money, etc.) I suggest looking at these topics for an intro into inferential statistics: 1) Sampling (random, stratified, etc) 2) Mean, variance/standard deviation, median, and mode 3) Data distributions 4) Confidence intervals 5) T-tests 6) Analysis of variance 7) Trend analysis (regression) 8) Association analysis ... and many more!
