You need to create two histograms: one for the pre-BMI intervention and another for the post-BMI intervention. | ||||||||
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. |
The histograms are:
BMI Before | BMI After | |
count | 20 | 20 |
mean | 25.90 | 25.30 |
sample standard deviation | 3.54 | 2.34 |
sample variance | 12.52 | 5.48 |
minimum | 21 | 22 |
maximum | 35 | 30 |
range | 14 | 8 |
skewness | 0.99 | 0.58 |
kurtosis | 1.13 | -0.21 |
coefficient of variation (CV) | 13.66% | 9.26% |
Both histograms are skewed to the right. The coefficient of variation is more for histogram 1. The mean is almost the same for both variables. The minimum values are also the same for both variables.
