Let's calculate the means for the male and female pulse rates given in the image.

### Male Pulse Rates:
96, 93, 54, 92, 66, 97, 63, 54, 58, 71, 63, 75, 54, 95, 70

To find the mean:
\[
\text{Mean for males} = \frac{\text{Sum of all male pulse rates}}{\text{Number of male pulse rates}}
\]

Let's calculate it.

### Female Pulse Rates:
72, 86, 86, 90, 71, 84, 94, 64, 88, 65, 79, 93, 75, 69, 82

Similarly, to find the mean:
\[
\text{Mean for females} = \frac{\text{Sum of all female pulse rates}}{\text{Number of female pulse rates}}
\]

I'll calculate both means now.The mean pulse rates are:

- The mean for males is **73.4** beats per minute.
- The mean for females is **79.9** beats per minute (rounded to one decimal place).

Would you like details on the calculation, or do you have any questions?

Here are some related questions to consider:
1. What is the median pulse rate for both males and females?
2. How do the medians compare between the two groups?
3. What is the range of pulse rates for each gender?
4. Are there any outliers in either the male or female pulse rates?
5. How does the standard deviation compare between the two groups?

**Tip:** When comparing data sets, considering both the mean and median can give a clearer picture of the central tendency, especially if the data contains outliers.

Listed below are pulse rates (beats per minute) from samples of adult males and females. Find the mean and median for each of the two samples and then compare the two sets of results. Does there appear to be a difference?

Learn how to calculate the mean and median pulse rates for samples of adult males and females. Compare the two sets of results to identify any differences. This exercise involves basic statistical concepts such as mean and median, suitable for students in Grades 6-8.
