Question

The following data points represent the total weight loss (in kilograms) for each member of Omar's Final Fitness Team. 61, 90, 31, 35, 69, 37, 78

a. Using the data, create a histogram.

Answer 1

To create a histogram using the given data points, you need to group the data into intervals and count the number of data points in each interval.

Step-by-step explanation:

To create a histogram using the given data points, you will need to group the data into intervals and then count the number of data points that fall within each interval. Here is the step-by-step process:

1. Determine the range of the data by subtracting the minimum value from the maximum value. In this case, the range is 90 - 31 = 59.
2. Decide on the number and width of the intervals. Generally, it's recommended to have around 5-15 intervals. For this example, let's use 8 intervals.
3. Calculate the width of each interval by dividing the range by the number of intervals. In this case, the width will be 59 / 8 = 7.375.
4. Start with the minimum value (31) and add the interval width to obtain the upper limit of the first interval. Repeat this process for each interval.
5. Create the histogram by drawing a bar for each interval, with the height of the bar representing the frequency (number of data points) within that interval.

Using the given data, here is an example of how the histogram might look:
