A clinical trial is run to assess the effects of different forms of regular exercise on HDL levels in persons between the ages of 18 and 29. Participants in the study are randomly assigned to one of three exercise groups - Weight training, Aerobic exercise or Stretching/Yoga – and instructed to follow the program for 8 weeks. Their HDL levels are measured after 8 weeks and are summarized below.
Exercise Group N Mean Std Dev
Weight Training 20 49.7 10.2
Aerobic Exercise 20 43.1 11.1
Stretching/Yoga 20 57.0 12.5

To assess the effects of different forms of regular exercise on HDL levels, a clinical trial was conducted. The trial involved participants between the ages of 18 and 29 who were randomly assigned to one of three exercise groups: Weight Training, Aerobic Exercise, or Stretching/Yoga. Each group followed their respective exercise program for a duration of 8 weeks. After this period, the participants' HDL levels were measured and summarized as follows:
Exercise Group: Weight Training
- Number of participants (N): 20
- Mean HDL level: 49.7
- Standard Deviation (Std Dev): 10.2
Exercise Group: Aerobic Exercise
- Number of participants (N): 20
- Mean HDL level: 43.1
- Standard Deviation (Std Dev): 11.1
Exercise Group: Stretching/Yoga
- Number of participants (N): 20
- Mean HDL level: 57.0
- Standard Deviation (Std Dev): 12.5
The mean HDL level represents the average HDL level observed in each exercise group. The standard deviation tells us how much the HDL levels vary within each group.
Using this data, one could compare the mean HDL levels among the different exercise groups to understand the potential effects of each exercise type on HDL levels. For example, based on the given data, it seems that the Weight Training and Aerobic Exercise groups have lower mean HDL levels compared to the Stretching/Yoga group. However, further analysis and statistical tests are typically required to determine if these observed differences are statistically significant or if they occurred by chance.
It's important to note that this explanation is based solely on the provided information and does not account for other factors like individual health conditions or lifestyle habits that could influence HDL levels.
