Does the frequency distribution appear to have a normal distribution using a strict interpretation of the relevant criteria. IQ score 50-69,70-89, 90-109, 110-129, 130-149 frequency 24, 228, 490, 232, 26

No, the distribution does not appear to be normal.

Yes, all the requirements are met.

No, the frequencies do not decrease from the maximum frequency to a low frequency.

No, the frequencies do not decrease from the maximum frequency to a low frequency

Fletcher Shields · Answer 2

Yes, all the requirements are met.

Step-by-step explanation:

Frequency Distribution is a graph or table which shows the frequency of different outcome.

Normal Distribution has bell like-shape.

Since here the value of frequency is less for score 50-69 then it increases from 70 - 109 then the frequency is again decreasing from score 110-149. So the curve of frequency distribution when plotted appears like bell-shaped. Hence, It appears like a normal distribution.
