Question

write true or false for the following statement.
a grouped frequency distribution has the same number of groups as there are data items.
choose the correct choice below.
a. false, because there are always more groups than data items.
b. false, because there can be multiple data items per group.
c. true, because a group is created for every data item.
d. true, because each data item belongs to only one group.

Explanation:

In a grouped frequency distribution, data items are grouped into intervals. Each group can contain multiple data items. For example, if data items are \(1,2,3,4,5,6\) and we make groups \(1 - 3\) and \(4 - 6\), there are 6 data items but 2 groups. So the number of groups is not the same as the number of data items.

Answer:

B. False, because there can be multiple data items per group.
