What is a box plot?

Back

A box plot is a graphical representation of a data set that shows the median, quartiles, and potential outliers.

Front

What does the median represent in a data set?

Back

The median is the middle value when the data set is ordered from least to greatest.

Front

How do you find the median of a data set?

Back

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

Front

What is interquartile range (IQR)?

Back

The interquartile range is the difference between the first quartile (Q1) and the third quartile (Q3) in a data set, representing the range of the middle 50% of the data.

Front

What does a higher median indicate about a data set?

Back

A higher median indicates that the central tendency of the data set is higher, meaning that more values are above the lower half of the data.

Front

What is variability in a data set?

Back

Variability refers to how spread out or clustered the data values are in a data set.

Front

How can you determine which dot plot has less variability?

Back

The dot plot with values that are closer together and less spread out has less variability.

Front

What happens to the mean when the highest score is removed from a data set?

Back

Removing the highest score typically decreases the mean, as the average is calculated from a smaller total.

Front

What is the mean of a data set?

Back

The mean is the average of a data set, calculated by adding all the values together and dividing by the number of values.

Front

What is a dot plot?

Back

A dot plot is a simple graphical display that uses dots to represent the frequency of data points in a data set.
