Determine Mode, Median, and Range of a Data Set

Front

What is the mode of a data set?

Back

The mode is the value that appears most frequently in a data set.

Front

How do you calculate the range of a data set?

Back

The range is calculated by subtracting the smallest value from the largest value in the data set.

Front

What is the median of a data set?

Back

The median is the middle value when the data set is ordered from least to greatest. If there is an even number of observations, the median is the average of the two middle numbers.

Front

What does it mean if a data set has no mode?

Back

If a data set has no mode, it means that no number appears more than once.

Front

How can you identify the mode in a data set with multiple modes?

Back

A data set with multiple modes is called multimodal, and it has two or more values that appear with the highest frequency.

Front

What is the significance of the median in a data set?

Back

The median provides a measure of central tendency that is less affected by outliers than the mean.

Front

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

Back

To find the median in a data set with an odd number of values, order the data and select the middle value.

Front

What is an outlier, and how can it affect the range?

Back

An outlier is a value that is significantly higher or lower than the other values in a data set. It can increase the range by widening the difference between the maximum and minimum values.

Front

What is the formula for calculating the range?

Back

Range = Maximum value - Minimum value.

Front

How do you determine if a data set is skewed based on the mode and median?

Back

If the mode is greater than the median, the data set is negatively skewed. If the mode is less than the median, it is positively skewed.
