Question

for out data set,what is the most frequent height?
A.63-65
B.65-66
C.66-68
D.68-70
E.70-71

Answer 1

I don’t have your data, so I can’t pick the correct option yet. Please paste the list of heights or the frequency table.

How to find the answer (choose one of the given class options):
- If you have raw heights: count how many times each height (or height interval) occurs; the interval with the highest count is the most frequent.
- If you have a grouped frequency table: the modal class is the class interval with the largest frequency. If you want a more precise (interpolated) mode for continuous grouped data, use:
Mode ≈ L + ((fm − f1) / (2fm − f1 − f2)) × h
where L = lower class boundary of the modal class, fm = frequency of the modal class, f1 = frequency of the class before, f2 = frequency of the class after, and h = class width.

One quick note: your class options overlap/are inconsistent (63–65 and 65–66 share 65). Tell me whether class endpoints are inclusive/exclusive or give class boundaries (e.g., 62.5–65.49, 65.5–66.49, etc.), or just provide the raw numbers and I’ll compute the most frequent height and pick A–E.
