Understanding Mean, Median, and Mode

What is the mean of the following numbers: 4, 8, 6, 5, 3?

• 4.5

• 6.0

• 7.2

• 5.2

Calculate the median of the set: 12, 15, 11, 14, 13.

• 12

• 15

• 14

• 13

In a data set, if the mode is 7, what does that indicate about the data?

• The number 7 is the most frequently occurring value in the data set.

• The number 7 appears only once in the data set.

• The number 7 is the average value of the data set.

• The number 7 is the smallest value in the data set.

Find the mean of these numbers: 10, 20, 30, 40, 50.

• 30

• 45

• 35

• 25

What is the median of the following list: 3, 1, 4, 2, 5?

• 2

• 3

• 4

• 5

If a data set has no repeating numbers, what can be said about its mode?

• The mode is the highest number.

• The mode is the average of the numbers.

• The mode is the sum of all numbers.

• The mode is undefined.

Determine the mode of the numbers: 2, 3, 4, 4, 5, 5, 5, 6.

• 3

• 6

• 5

• 4

What is the mean of the following values: 1, 2, 3, 4, 5, 6, 7, 8, 9?

• 6

• 10

• 4

• 5

How do you find the median in a data set with an even number of values?

• The median is the average of the two middle values.

• The median is the largest value in the data set.

• The median is the sum of all values divided by the number of values.

• The median is the smallest value in the data set.

If the mean of a data set is 10 and the mode is 8, what can you infer about the distribution?

• The distribution is uniform.

• The distribution is normal.

• The distribution is likely negatively skewed.

• The distribution is likely positively skewed.
