Find the mean, median, and mode of the data set. Round to the nearest tenth. 15, 13, 9, 9, 7, 1, 11, 10, 13, 1, 13
mean = 8.5, median = 10, mode = 8
mean = 9.3, median = 10, mode = 13 mean = 8.5, median = 10, mode = 13 mean = 9.3, median = 8, mode =13
Mode = most frequently occurring score, 13
Median = arrange in order of value and choose the middle-most score.
Mean = Add the values of the scores and divide by the number of scores.
To find the mean, median, and mode of a data set, follow these steps:
Mean:
1. Add up all the numbers in the data set: 15 + 13 + 9 + 9 + 7 + 1 + 11 + 10 + 13 + 1 + 13 = 102
2. Divide the sum by the total number of values in the data set: 102 / 11 ≈ 9.3
So the mean is approximately 9.3.
Median:
1. Arrange the values in numerical order: 1, 1, 7, 9, 9, 10, 11, 13, 13, 13, 15
2. Since there are 11 values, the middle value(s) will give us the median. In this case, the two middle values are 9 and 10.
3. Find the average of the two middle values: (9 + 10) / 2 = 19 / 2 = 9.5
So the median is 9.5.
Mode:
1. The mode is the value(s) that occur(s) most frequently in the data set.
2. In this case, the number 13 appears three times, which is more frequent than any other number.
3. Therefore, the mode is 13.
So, the correct answer would be mean = 9.3, median = 9.5, and mode = 13.
Look up your definitions.
Since 13 appears 3 times, the most times, 13 must be the mode
For the median, arrange them in order, pick the one in the middle
For the mean, just add them all up, then divide by 11
I am not going to do the arithmetic for you.
