13.7 Stem & Leaf Plots

What is a stem-and-leaf plot?

• A method of displaying qualitative data in a tabular format.

• A method of displaying quantitative data in a graphical format, similar to a histogram, to retain the original data values while showing their distribution.

• A type of chart used to represent categorical data.

• A graphical representation of data using bars to show frequencies.

What does the 'stem' represent in a stem-and-leaf plot?

• The leading digit(s) of the data values.

• The trailing digit(s) of the data values.

• The average of the data values.

• The median of the data values.

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

• To organize data to easily visualize its distribution and identify patterns.

• To create a graphical representation of data using bars.

• To calculate the mean and median of a data set.

• To display data in a circular format.

What is the relationship between stem-and-leaf plots and box plots?

• Both are used to summarize data distributions, but stem-and-leaf plots show individual data points while box plots summarize data through quartiles.

• Stem-and-leaf plots are used for categorical data, while box plots are used for numerical data.

• Both plots display the same information but in different formats without any additional insights.

• Stem-and-leaf plots are more complex and less informative than box plots.

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

• It indicates the scale of the data represented by each leaf.

• It shows the total number of data points in the plot.

• It represents the average value of the data set.

• It determines the range of the data values.

What is the mode of a data set?

• The value that appears most frequently in a data set.

• The average of all values in a data set.

• The middle value when the data set is ordered.

• The highest value in a data set.

How can you identify the mode using a stem-and-leaf plot?

• By looking for the stem with the most leaves.

• By counting the total number of leaves.

• By identifying the longest stem.

• By finding the average of the leaves.

What does the 'leaf' represent in a stem-and-leaf plot?

• The leading digit(s) of the data values.

• The trailing digit(s) of the data values.

• The average of the data values.

• The maximum value in the data set.

What is the first step in creating a stem-and-leaf plot?

• To plot the data points on a graph.

• To separate each data value into a stem and a leaf.

• To calculate the mean of the data set.

• To arrange the data in ascending order.

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

• To interpret, read the stems vertically and the leaves horizontally to understand the distribution of data.

• To interpret, read the leaves vertically and the stems horizontally to understand the distribution of data.

• To interpret, analyze the median and mode of the data without using the plot.

• To interpret, convert the plot into a bar graph for better visualization.
