Define and explain what a distribution is and how its shape affects our analysis of the data.
What will be an ideal response?
A distribution is a set of scores collected as data. The shape of a distribution can take many forms, but two common shapes are symmetrical and skewed shapes. These shapes will affect our choice of both descriptive and inferential statistics. Skew in a distribution can affect the comparison of different measures of what is considered a typical score. Many distributions, however, show clustering of scores toward the top or bottom end of the scale. In fact, without "curving", grade distributions in many college courses show a clustering of grades toward the high end of the grade scale, often because there are more people in a course who do well than who do very poorly.
