8. Given the following VO2 (in ml/kg/min) data set for a group of trained and a group of untrained athletes, calculate the mean for each group. Trained Athletes: 70, 62, 58, 65, 61, 68, 72, 55 Untrained Athletes: 55, 52, 48, 53, 46, 42, 51, 58 Plot the mean data using the appropriate type of graph and answer the following questions: a. What are the independent and dependent variables in this graph? Which variable goes on each of the X-axis and the Y-axis? b. Write a few sentences to describe these results. Is there a difference in VO₂ between these two groups? If yes, describe the difference.

Question
Transcribed Image Text:**Educational Content:**
**Topic:** Understanding VO₂ Data Sets and Graph Interpretation
**Task 8: VO₂ Data Analysis**
Given the following VO₂ (in ml/kg/min) data set for a group of trained and a group of untrained athletes, calculate the mean for each group.
- **Trained Athletes:** 70, 62, 58, 65, 61, 68, 72, 55
- **Untrained Athletes:** 55, 52, 48, 53, 46, 42, 51, 58
**Instructions:**
1. Plot the mean data using the appropriate type of graph and answer the following questions:
**Questions:**
a. **Independent and Dependent Variables:**
- Identify the independent and dependent variables in this graph. Indicate which variable should be placed on the X-axis and which on the Y-axis.
b. **Results Description:**
- Analyze the results by writing a few sentences. Is there a difference in VO₂ between these two groups? If yes, describe the difference.
**Graph Description:**
- The graph should display two bars, one for each group ('Trained Athletes' and 'Untrained Athletes') with their respective mean VO₂ values on the Y-axis. The X-axis will indicate the group category.
