How do you find the Median of a data set?

Back

To find the median, arrange the data in ascending order and locate the middle value. If there is an even number of values, average the two middle values.

Front

What is the Range of a data set?

Back

The range is the difference between the maximum and minimum values in a data set.

Front

What is the Minimum Value in a data set?

Back

The minimum value is the smallest number in the data set.

What is the Maximum Value in a data set?

Back

The maximum value is the largest number in the data set.

Front

What is the Interquartile Range (IQR)?

Back

The Interquartile Range is the difference between the first quartile (Q1) and the third quartile (Q3) in a data set.

Front

What does the first quartile (Q1) represent?

Back

The first quartile (Q1) represents the median of the lower half of the data set, meaning 25% of the data falls below this value.

Front

What does the third quartile (Q3) represent?

Back

The third quartile (Q3) represents the median of the upper half of the data set, meaning 75% of the data falls below this value.

Front

How do you calculate the Interquartile Range (IQR)?

Back

IQR = Q3 - Q1.

Front

What does it mean if a data set is skewed?

Back

A data set is skewed if it is not symmetrical, meaning one tail is longer or fatter than the other.
