Exploring Mean, Median, Mode, and Range

Miss Kilburn introduces the concepts of mean, median, mode, and range as part of a data analysis unit. She explains how to calculate each measure with examples, discusses outliers, and provides practice problems. The video emphasizes understanding these statistical concepts and applying them to data sets.

What is the first step in calculating the mean of a set of numbers?

• Add all the numbers together

• Arrange the numbers in ascending order

• Divide the sum by the number of elements

• Identify the largest number

What value do you get when you calculate the mean of the numbers 20, 13, 22, 17, and 28?

• 18

• 20

• 19

• 21

Which number is considered an outlier in the given set: 0, 5, 6, 12, 18, 99?

• 99

• 12

• 18

• 6

In a dataset, if two numbers appear most frequently, what are they considered in terms of mode?

• Both are outliers

• Neither is the mode

• Both are the mode

• It's inconclusive

How do you find the median in a set of numbers?

• Subtract the smallest number from the largest

• Arrange the numbers and choose the middle one

• Choose the number that appears most frequently

• Divide the sum of all numbers by their count

What is the median of the numbers 10, 13, 20, 16, and 24 when arranged in order?

• 16

• 15

• 20

• 13

What is the range of a dataset that includes the numbers 3 and 80?

• 77

• 83

• 80

• 3

If a dataset's largest number is 84 and the smallest is 0, what is the range?

• 0

• 168

• 84

• 42

What is the mean of the numbers 15, 16, 29, 33, 22, and 133?

• 41.3

• 24.8

• 29.5

• 33.0

After arranging the numbers 7, 12, 3, 11, 17, and 20 in order, what is the median?

• 9

• 10

• 11

• 12
