How do you read a stem-and-leaf plot?

Back

In a stem-and-leaf plot, the 'stem' represents the leading digit(s) and the 'leaf' represents the last digit. For example, in '3 | 4', '3' is the stem and '4' is the leaf, representing the number 34.

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

Back

A dot plot skewed to the right means that most of the data points are concentrated on the left side, with fewer points on the right.

Front

How can you determine the range of a dataset?

Back

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

What is the purpose of using a stem-and-leaf plot?

Back

A stem-and-leaf plot helps to visualize the shape of the data distribution while retaining the original data values.

Front

How do you create a frequency table?

Back

To create a frequency table, list all unique values in one column and count how many times each value appears in the dataset in the next column.

What is the difference between a dot plot and a bar graph?

Back

A dot plot uses dots to represent individual data points, while a bar graph uses bars to show the frequency of data in categories.
