Class A had a mean score of 7.6 and a standard deviation of 0.7
Class B had a mean score of 7.7 and a standard deviation of 0.6

Which class scored better on average? Select an answer Class A Class B 

Which class had more consistent scores?

### Answer

1. **Which class scored better on average?**  
   - **Class B** scored better on average, as it had a mean score of 7.7 compared to Class A's mean score of 7.6.

2. **Which class had more consistent scores?**  
   - **Class B** had more consistent scores. Consistency in scores is indicated by a lower standard deviation, and Class B has a standard deviation of 0.6, which is lower than Class A's standard deviation of 0.7.

### Summary:
- **Class B** scored slightly better on average.
- **Class B** had more consistent scores.

Would you like further clarification or details on any of these points?

Here are five related questions to expand on these concepts:

1. What is the significance of the standard deviation in evaluating consistency?
2. How would the range of scores differ between these two classes, given their standard deviations?
3. If a third class had a mean of 7.5 and a standard deviation of 0.5, how would it compare to Classes A and B?
4. Can we calculate the probability of a score falling within one standard deviation of the mean for each class?
5. How does the mean and standard deviation relate to the overall distribution of scores?

**Tip:** A smaller standard deviation indicates that data points are closer to the mean, showing more consistency.

Class A had a mean score of 7.6 and a standard deviation of 0.7. Class B had a mean score of 7.7 and a standard deviation of 0.6. Which class scored better on average? Select an answer: Class A or Class B. Which class had more consistent scores?

Analyze which class scored better on average and which class had more consistent scores by comparing the mean and standard deviation for Class A and Class B. Class B has a slightly higher mean of 7.7 and a lower standard deviation of 0.6, indicating better average performance and consistency.
