What is the median in 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 values, the median is the average of the two middle numbers.

Front

How do you find the range of a data set?

Back

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

Front

What does it mean if data is clustered?

Back

A cluster in data refers to a grouping of data points that are close together, indicating that there are many values in that range.

Front

What is a skewed distribution?

Back

A skewed distribution is one where the data points are not symmetrically distributed around the mean. It can be skewed left (negatively) or skewed right (positively).

Front

What does it mean if a distribution is skewed right?

Back

If a distribution is skewed right, it means that the majority of data values fall to the left of the mean, with a long tail extending to the right.

Front

What is a symmetric distribution?

Back

A symmetric distribution is one where the left and right sides of the data are mirror images of each other, meaning the mean, median, and mode are all equal.

Front

What is the mode of a data set?

Back

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

Front

What is a peak in a data display?

Back

A peak in a data display refers to a point where the frequency of data points is at its highest, indicating a concentration of values.

Front

What is a gap in a data display?

Back

A gap in a data display is a space where there are no data points, indicating a range of values that are not represented in the data set.

Front

How do you identify outliers in a data set?

Back

Outliers are values that are significantly higher or lower than the majority of the data points. They can be identified using statistical methods such as the interquartile range.
