1.                  Define a “population” in your own words.

2.                  Define “discrete and quantitative data” in your own words.

3.                  Describe what “overlapping classes” are in a “frequency distribution” in your own words.

4.                  Define “mean” in your own words.

5.                  Describe the difference between these types of distributions:

a.      Left (negatively) skewed

b.      Symmetrical (Normal)

c.      Bimodal

d.      Right (positively) skewed

Solution

1.

A population is the set of all data points which you want to generally describe.

2.

Discrete data can only take certain values on an interval, while continuous data can take any value on an interval.

For example, the number of eggs in a basket is discrete, because it cannot take decimal values (like 6.3 eggs). Meanwhile, height is continuous because it can take any value on a reasonable interval, any height greater than 0.
