Unit 6 Lesson 1: Measures of Spread and Distribution

Which distribution types are Symmetrical?

• Bell-Shaped

• Symmetrical

• Bimodal

• Skewed

• Uniform

What type of distribution does this graph represent?

• Bell-Shaped

• Symmetrical

• Bimodal

• Skewed

• Uniform

What type of distribution does this graph represent?

• Bell-Shaped

• Symmetrical

• Skewed Left

• Skewed Right

Consider the distribution type of this graph, which Measure of Center would fit it best?

• Mean

• Median

Consider the distribution type of this graph, which Measure of Center would fit it best?

• Mean

• Median

What types of data distributions exist? Check all that apply.

• Symmetric (bell-shaped)

• Skewed

• Bimodal

• Uniform

• Average

In a uniform distribution...(check all that apply)

• data values are skewed

• data values are evenly distributed

• mean = median

• frequency of each data point is the same

In a skewed distribution...

• data can only skew to the right

• mean = median

• Data points do not follow any pattern

• one side of the distribution has more values farther from the bulk of the data than the other side.

Bimodal distributions...

• has two very common data values (peaks) seen in a dot plot or histogram

• are always symmetric

• mean = median

• may be skewed to the right of to the left

3, 4, 5, 5, 5, 6,7
The mode of these numbers is

• 5
• 10
• 4
• 1
