I do not understand this?
I will do one for you, then you ask with your work on the others.
3. Put them in order:
12,20,24,34,60
range 12 to 60
no mode
mean: add them up and divide by 5
median: 24
To find the mean, median, mode, and range of each set of data, follow these steps:
1. Mean:
- Add up all the numbers in the set of data.
- Divide the sum by the total number of values in the set.
2. Median:
- Arrange the numbers in ascending order.
- If there is an odd number of values, the median is the middle number.
- If there is an even number of values, the median is the average of the two middle numbers.
3. Mode:
- The mode is the number(s) that appear(s) most frequently in the set of data.
- If there is no number that appears more than once, the set is considered to have no mode.
4. Range:
- The range is the difference between the highest and lowest values in the set of data.
Let's apply these steps to the given data sets:
1. 34, 41, 37, 29, 34
- Mean: (34 + 41 + 37 + 29 + 34) / 5 = 175 / 5 = 35
- Median: Arrange the numbers in ascending order: 29, 34, 34, 37, 41. The median is 34.
- Mode: 34 appears twice, so the mode is 34.
- Range: The highest value is 41, and the lowest value is 29. The range is 41 - 29 = 12.
2. 9, 21, 93, 31, 31
- Mean: (9 + 21 + 93 + 31 + 31) / 5 = 185 / 5 = 37
- Median: Arrange the numbers in ascending order: 9, 21, 31, 31, 93. The median is 31.
- Mode: 31 appears twice, so the mode is 31.
- Range: The highest value is 93, and the lowest value is 9. The range is 93 - 9 = 84.
3. 34, 20, 24, 12, 60
- Mean: (34 + 20 + 24 + 12 + 60) / 5 = 150 / 5 = 30
- Median: Arrange the numbers in ascending order: 12, 20, 24, 34, 60. The median is 24.
- Mode: There are no repeated numbers, so there is no mode.
- Range: The highest value is 60, and the lowest value is 12. The range is 60 - 12 = 48.
4. 74, 92, 67, 45, 67
- Mean: (74 + 92 + 67 + 45 + 67) / 5 = 345 / 5 = 69
- Median: Arrange the numbers in ascending order: 45, 67, 67, 74, 92. The median is 67.
- Mode: 67 appears twice, so the mode is 67.
- Range: The highest value is 92, and the lowest value is 45. The range is 92 - 45 = 47.
