1. How to describe a graph Otherwise called CUSS
Do after Features of Distributions Activity

2. 3. Shape of the Distribution
refers to the overall type of the distribution
symmetrical, uniform, normal, skewed, or bimodal

3. Symmetrical
refers to data in which both sides are (more or less) the same when the graph is folded vertically down the middle
bell-shaped is a special type
has a center mound with two sloping tails

4. Shape----Bell-shaped curve----Symmetric
Descriptive Terms of Sampling Distribution (Histogram) and Model (Red Curve)
Shape----Bell-shaped curve----Symmetric

5. Uniform
refers to data in which every class has equal or approximately equal frequency

6. Uniform Population Model
Total area under the curve (model)
will always equal 1.

7. Skewed (left or right)
refers to data that is spread far and thinly toward one side
the direction of skewness is on the side of the longer tail

8. Descriptive Terms of Population Models
Two Examples of Skewed Right

9. Bimodal (multi-modal)
refers to data in which two (or more) classes have the largest frequency & are separated by at least one other class

10. Bi-Modal Data
