When a frequency polygon has a sharp peak near the center,and very few scores away from the center,you would expect that
A) the mode for the data set will be greater than the mean.
B) the standard deviation for the data set will be high.
C) the standard deviation for the data set will be low.
D) the mean for the data set will be less than the median.

Question

Quizplus · Accepted Answer

When a frequency polygon has a sharp peak near the center and very few scores away from the center, it indicates that the data is clustered closely around the center. This means that the standard deviation for the data set will be low. Option A is incorrect because the mode can be less than, greater than or equal to the mean value. Option B is incorrect because a sharp peak indicates there are not many scores that are far from the mean, thus indicating a low standard deviation. Option D is incorrect because it is not possible to deduce the relationship between the mean and the median based on the shape of the frequency polygon alone.
