Find the mean, median and mode of the following set of data.​         6.1, 5.2, 7.2, 7.2, 3.6, 9.0, 6.5, 7.4, 5.46.1,\ 5.2,\ 7.2,\ 7.2,\ 3.6,\ 9.0,\ 6.5,\ 7.4,\ 5.46.1, 5.2, 7.2, 7.2, 3.6, 9.0, 6.5, 7.4, 5.4

To find the mean, median, and mode of the data set, follow these steps:

Mean:

1. Add all the numbers together: 6.1 + 5.2 + 7.2 + 7.2 + 3.6 + 9.0 + 6.5 + 7.4 + 5.4 = 57.6
2. Divide the sum by the total number of data points: 57.6 / 9 = 6.4 So, the mean of the data set is 6.4.

Median:

1. Arrange the data points in ascending order: 3.6, 5.2, 5.4, 6.1, 6.5, 7.2, 7.2, 7.4, 9.0
2. Find the middle number. Since there are 9 data points, the middle number is the 5th number, which is 6.5. So, the median of the data set is 6.5.

Mode:

1. Identify the number that appears most frequently in the data set. In this case, 7.2 appears twice. So, the mode of the data set is 7.2.
