Mean
The average value you get when you add up all the numbers and divide by how many numbers there are.
What is the mean?
This is the middle value in a set of data when written in order.
What is the median?
This measure of central tendency can have more than one value in a data set.
What is the mode?
In a data set, the difference between the highest and lowest values.
What is the range?
Name three main measures of central tendency.
What are mean, median, and mode?
Find the mean of these numbers: 5, 10, 15.
What is 10?
What is the median of the set: 3, 5, 1?
What is 3?
Identify the mode for the list: 6, 6, 9, 11, 11, 11, 13.
What is 11?
Calculate the range of the numbers: 5, 15, 25, 35.
What is 30?
Why might the mean not always be a representative measure of a data set?
What is it can be affected by extreme values or outliers?
Calculate the mean for the set: 7, 14, 21, 28, 35.
What is 21?
Find the median of the data set: 8, 3, 12, 5, 7.
What is 7?
If a dataset has multiple values all occurring the same number of times, what is this called?
What is it has no mode or is multimodal?
If the maximum value is 50 and the minimum value is 12, what is the range?
What is 38?
Which measure of central tendency is least affected by outliers?
What is the median?
If the numbers 12, 15, and 20 are changed to 22, 25, and 30, how does the mean change?
What is "the mean increases"?
When a data set has an even number of values, how is the median calculated?
What is "the median is the average of the two middle numbers"?
The result when you find the mode of 18, 22, 22, 15, 18, 15, 22.
What is 22?
How does the range help in understanding data variability?
What is the range measures the spread or dispersion of the dataset?
In what scenario is the mode the best measure of central tendency?
What is when the most common item is of interest, such as shoe size or preferred product?
If the mean of six numbers is 9, what is their total sum?
What is 54?
For the data set 20, 15, 25, 30, 10, calculate the median.
What is 20?
Explain why a set of data might not have a mode.
What is there are no repeating numbers?
Find the range of this data set: 44, 33, 67, 22, 89.
What is 67?
Name a situation where all three measures of central tendency give the same result.
What is a perfectly symmetrical bell-shaped distribution?
