Back

Visual overlap refers to the range of values that two or more data sets share when represented visually, such as on a graph.

What does IQR stand for and what does it represent?

Back

IQR stands for Interquartile Range, which measures the spread of the middle 50% of a data set.

Front

How do you determine the median of a data set?

Back

To find the median, arrange the data in numerical order and identify the middle value.

Front

What is the range of a data set?

Back

The range is the difference between the highest and lowest values in a data set.

Front

What does it mean if a data set is symmetric?

Back

A symmetric data set has a balanced distribution, where the left and right sides of the graph are mirror images.

Front

What is a measure of center in statistics?

Back

A measure of center is a value that represents the center point of a data set, commonly the mean, median, or mode.

Front

What does a smaller range indicate about a data set?

Back

A smaller range indicates that the values in the data set are closer together, suggesting more consistency.

Front

What is the significance of visual overlap in comparing data sets?

Back

Visual overlap helps to identify similarities and differences between data sets, indicating how much they share in common.

Front

How can you tell which class has more consistent test scores?

Back

You can determine consistency by comparing the ranges or IQRs of the test scores; a smaller range or IQR indicates more consistency.
