Question

which descriptions of a histogram are true? check all that apply..
□ a peak is a bar that is lower than the other bars around it.
□ a peak is where the frequency is lowest.
□ a peak is where the frequency is the highest.
□ a cluster is a group of bars, meaning the frequency is higher in these intervals.
□ a peak is a bar that is higher than the other bars around it.
□ intervals on a histogram where there are no bars mean the frequency is 0.
□ if the graph is symmetrical, the data is clustered toward the right side.
□ if the graph is symmetrical, the data is evenly distributed.

Explanation:

• A peak in a histogram refers to the bar (or interval) with the highest frequency, so it is taller than surrounding bars.
• A cluster is a group of adjacent bars with relatively high frequency compared to other intervals.
• Empty intervals (no bars) mean there are no data points in that range, so frequency is 0.
• Symmetrical histograms have data evenly distributed around the center, not clustered to one side.

Answer:

C. A peak is where the frequency is the highest.
D. A cluster is a group of bars, meaning the frequency is higher in these intervals.
E. A peak is a bar that is higher than the other bars around it.
F. Intervals on a histogram where there are no bars mean the frequency is 0.
H. If the graph is symmetrical, the data is evenly distributed.
