What is a stem-and-leaf plot?

Back

A stem-and-leaf plot is a method of displaying quantitative data in a graphical format, similar to a histogram, to retain the original data values while showing their distribution.

How do you find the mean of a data set?

Back

What is the mode in a data set?

Back

The mode is the value that appears most frequently in a data set.

Front

How do you determine the median of a data set?

Back

Front

What does a dot plot represent?

Back

A dot plot is a simple way to display data points along a number line, where each dot represents one occurrence of a value.

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

Back

The stem represents the leading digit(s) of the data values, while the leaves represent the trailing digits.

Front

How can you identify the range of a data set?

Back

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

Front

What is the difference between mean and median?

Back

The mean is the average of all data points, while the median is the middle value when the data is ordered.

Front

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

Back

To interpret a stem-and-leaf plot, read the stems vertically and the leaves horizontally to understand the distribution and frequency of the data.

Front

What is the significance of the mode in data analysis?

Back

The mode indicates the most common value in a data set, which can be useful for understanding trends and patterns.
