Analyzing Data Distributions Quiz

What are the two main aspects you can learn about when analyzing data distributions?

• Describing the size and weight of a distribution

• Describing the height and width of a distribution

• Describing the center and spread of a distribution

• Describing the shape and color of a distribution

Which of the following is NOT a key statistical term used to describe data distributions?

• Median

• Cluster

• Gap

• Peak

What is a peak in a data distribution?

• A data value that is 1.5 times the interquartile range from the quartiles

• The most frequently occurring value or interval of values

• A group of data values clustered together

• A region where there are no data values

How can you determine if a distribution is symmetric?

• By checking if the left side is taller than the right side

• By checking if the left side looks like the right side

• By counting the number of outliers

• By identifying the number of peaks

If a distribution has an outlier, what can be said about its symmetry?

• The distribution has no gaps

• The distribution has multiple peaks

• The distribution is not symmetric

• The distribution is symmetric

In the guided example, what was identified as the peak in the distribution of adult cat weights?

• 10

• 14

• 12

• 7

Which measure is affected by outliers when describing the center of a distribution?

• Mean

• Median

• Mode

• Range

When a distribution is not symmetric, which measures should be used to describe the center and spread?

• Mode and range

• Mean and range

• Median and interquartile range

• Mean and mean absolute deviation

In the guided example, what was the median of the high temperatures in various cities?

• 95

• 100

• 84

• 80

What is the mean absolute deviation rounded to the nearest tenth in the example of dance students' practice hours?

• 1.3

• 1.2

• 1.4

• 1.1
