True or False: The median is always the highest number in a data set.

False. The median is the middle number when the data is arranged in order, not necessarily the highest.

Riddle: I am a number that represents the center of a data set when arranged, and I can be the average of two numbers if there is an even amount. What am I?

Fill in the blank: The mean of a set of numbers can be affected by very high or low ______.

Values

Which of the following represents the median for the set {2, 4, 6, 8, 10}? A) 4 B) 5 C) 6 D) 8

C) 6

What should you do first when finding the median?

Arrange the numbers in ascending order.

True or False: The mean is always less than the median in a data set.

False. The relationship between mean and median depends on the data distribution.

Riddle: I can be calculated by adding a set of numbers and dividing by the total count. What am I?

Which measure is better for understanding typical values when there are extreme outliers, mean or median?

Median

True or False: The mean of a data set can be a decimal.

True. The mean can be a decimal depending on the numbers in the set.

Riddle: I am the number that lies in the center, but only when the data is sorted from least to greatest. What am I?

8

In a data set of 10 numbers, how do you find the median?

Average the 5th and 6th numbers after arranging the data in order.

Which measure of central tendency is less affected by extreme values: mean or median?

Median

True or False: The mean and median will always be the same in a data set.

False. They can differ, especially in skewed distributions.

Riddle: I represent the average but can be skewed by a few high numbers. Who am I?
