Thank you, Ms.Sue.
You're welcome.
To find the mean for the given data, follow these steps:
1. Add up all the numbers in the data: 19 + 19 + 14 + 14 + 16 + 19 + 19 + 16 + 16 + 15 + 17 + 16 + 17 + 16 + 15 + 14 + 15 + 15 + 17 + 14 + 16 + 15 = 352.
2. Count the number of data points in the set: There are 22 data points.
3. Divide the sum of the data points by the total number of data points: 352 / 22 = 16.
4. Round the result to the nearest tenth: The mean for the data is 16.0.
To find the median for the given data, follow these steps:
1. Arrange the data points in ascending order: 14, 14, 14, 15, 15, 15, 15, 15, 16, 16, 16, 16, 16, 16, 17, 17, 17, 19, 19, 19, 19, 19.
2. Count the number of data points: There are 22 data points.
3. Since there are an even number of data points, the median is the average of the middle two values.
- The two middle values are 16 and 16, so the median is (16 + 16) / 2 = 16.
To find the mode for the given data, follow these steps:
1. Look for the most frequently occurring value in the data.
2. In this case, the mode is the value that appears the most times.
- The value 16 appears 6 times, which is more than any other value.
3. Therefore, the mode for the data is 16.
