What does a stem represent in a stemplot?

Back

All but the final digit of a data value.

Front

What should be done if there is no data value for a particular stem in a stemplot, but there is data for the stem above and the stem below?

Back

Include the stem, but leave it empty.

Front

What does splitting stems in a stemplot help with?

Back

Showing the shape of the distribution more clearly.

Front

How do you interpret a stemplot?

Back

A stemplot displays quantitative data by separating each value into a stem (the leading digit) and a leaf (the trailing digit).

Front

What is the purpose of a stemplot?

Back

To visualize the distribution of a dataset while retaining the original data values.

Front

How can you determine the mode from a stemplot?

Back

The mode is the stem with the most leaves, indicating the most frequently occurring data value.

Front

What is the median in a dataset?

Back

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

Front

How do you find the median from a stemplot?

Back

Count the total number of leaves and find the middle leaf.

Front

What does it mean if a stemplot is skewed to the right?

Back

It indicates that there are a few high values that are pulling the mean to the right.

Front

What is the range of a dataset?

Back

The range is the difference between the highest and lowest values in the dataset.
