You need to create two HISTOGRAMS: one for Group 1 and
another for Group 2. The results reflect the heaviest
single lift between 2 groups of 30 participants as part of a
strength building program. |
||||||||

Please provide your interpretation of the results. For example, you might want to compare | ||||||||

the two histograms and point out the similarties and differences. You may want to share some | ||||||||

relevant descriptive statistics about the two groups of data. |

Answer #1

COMMENT: MEAN AND MEDIAN ARE APPROXIMATELY EQUAL DATA ARE NORMALLY DISTRIBUTED.

COMMENT:As we can see from our histogram for group 2 data as most values are clustered around the left tail of the distribution while the right tail of the distribution is longer. Also MEAN >MEDIAN

If we compare these two distribution we will find that Histogram for group 2 is showing more dispersion as compared to Histogram for group 1.
