Question

Construct a frequency distribution and a frequency histogram for the data set using the indicated number of classes. Describe any patterns. Number of​ classes: 8 Data​ set: Reaction times​ (in milliseconds) of 30 adult females to an auditory stimulus

Answer 1

Hello The data set is missing below is the missing data set

507,389,305,291,336,310,514,442,373,428,387,454,323,441,388,426,411,382,320,450,309,416,359,388,307,337,469,351,422,413

Explanation:

Data set:

507,389,305,291,336,310,514,442,373,428,387,454,323,441,388,426,411,382,320,450,309,416,359,388,307,337,469,351,422,413

To CONSTRUCT a Frequency Distribution do the following

• Identify the Number of classes ( 8 ).

• Find the data range ( 514-291) = 223

• Find the width 223/8 = 27.9. ≈ 28
• create 8 groups each of 28 width starting from (291).

• count the no of data set in each interval and use that to generate the frequency table as attached below

attached is the frequency table and histogram representation
