Stem and Leaf Plots

How do you count frequencies in a stem and leaf plot?

• Count the number of leaves associated with each stem to determine the frequency of each value.

• Count the number of stems to find the total number of values.

• Add all the leaves together to get the frequency.

• Count the number of unique values in the plot.

What is a stem and leaf plot?

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

• A graphical representation of data that retains original values while showing distribution.

• A type of chart used exclusively for categorical data.

• A statistical tool used for calculating averages.

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

• The leaf represents the leftmost digit(s) of the data values.

• The leaf represents the rightmost digit(s) of the data values.

• The leaf represents the average of the data values.

• The leaf represents the median of the data values.

What is the minimum value in a data set?

• The largest number in the data set.

• The average of all numbers in the data set.

• The smallest number in the data set.

• The median value of the data set.

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

• The leaf provides detailed information about the data values, allowing for a more precise understanding of the distribution.

• The leaf represents the median of the data set.

• The leaf is used to calculate the mode of the data set.

• The leaf indicates the range of the data values.

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

• The stem represents the leftmost digit(s) of the data values.

• The stem represents the rightmost digit(s) of the data values.

• The stem represents the average of the data values.

• The stem represents the total number of data values.

What is the range of a data set?

• The average of all values in the data set.

• The difference between the maximum and minimum values in the data set.

• The sum of all values in the data set divided by the number of values.

• The highest value in the data set.

How do you create a stem and leaf plot from a data set?

• Separate each data value into a stem and a leaf, then organize the stems in ascending order and list the corresponding leaves.

• Plot each data point on a graph and connect them with lines.

• Calculate the mean and median of the data set before plotting.

• Use a bar graph to represent the data visually.

How do you determine the mode from a stem and leaf plot?

• The mode is the average of the data set.

• The mode is the value that appears most frequently in the data set, which can be identified by looking for the leaf with the most entries.

• The mode is the middle value when the data is ordered.

• The mode is the highest value in the data set.

How can you find the median from a stem and leaf plot?

• By calculating the average of all data values.

• By listing all the data values in order and locating the middle value.

• By selecting the highest value in the plot.

• By counting the number of leaves in the plot.
