What is a stem-and-leaf plot and what information does it provide?

Back

A stem-and-leaf plot is a method of displaying quantitative data in a graphical format, similar to a histogram. It shows the distribution of data while preserving the original data values, with 'stems' representing the leading digits and 'leaves' representing the trailing digits.

How do you calculate the difference between the highest and lowest values in a data set?

Back

To calculate the difference between the highest and lowest values in a data set, subtract the smallest value (minimum) from the largest value (maximum).

What is the purpose of using plots like dot plots and stem-and-leaf plots in statistics?

Back

The purpose of using plots like dot plots and stem-and-leaf plots is to visually represent data, making it easier to identify patterns, trends, and distributions within the data set.

Front

How can you interpret the data from a dot plot?

Back

To interpret data from a dot plot, observe the number of dots at each value, identify clusters or gaps in the data, and analyze the overall shape of the distribution.
