Exploring Mean, Median, Mode, and Range

What is the learning target of this lesson?

• I can identify prime numbers.

• I can summarize numerical data by calculating the mean, median, mode, and range.

• I can calculate the sum of numbers.

• I can solve algebraic equations.

How do you calculate the mean of a data set?

• Add all the numbers and divide by the number of data values.

• Find the middle number of the data set.

• Identify the number that occurs most often.

• Subtract the smallest value from the largest value.

In the example given, what is the mean of the data set?

• 50

• 60

• 80

• 70

What is the median of a data set?

• The sum of all numbers divided by the number of data values.

• The middle number when the data is ordered from least to greatest.

• The number that occurs most often.

• The difference between the largest and smallest values.

If there are two middle numbers in a data set, how do you find the median?

• Multiply them together.

• Choose the smaller number.

• Choose the larger number.

• Add them and divide by two.

What is the mode of a data set?

• The sum of all numbers divided by the number of data values.

• The middle number when the data is ordered from least to greatest.

• The difference between the largest and smallest values.

• The number that occurs most often.

How do you calculate the range of a data set?

• Subtract the smallest value from the largest value.

• Identify the number that occurs most often.

• Find the middle number of the data set.

• Add all the numbers and divide by the number of data values.
