A club president records the ages of the members in a club and wants to group the data in intervals of 2 years. Should the president use a stem-and-leaf plot or a histogram? Explain.
The president should use a histogram.
A club president records the age of the members in a club and wants to group the data in intervals of two years.
The president should use a histogram, because age generally consists of two digits, and in a stem-and-leaf diagram it will be difficult to compare data in intervals of 2, as in the stem part the first digit is to written so data with intervals of 10 will be easy to understand.
In a histogram, the data in intervals of 2 will be easy to graph, the information will be clear and the president can quickly compare the number of members in each age group.
