### Instruction: help me answer this question Find the variance of the following data: 2.25, 21, 24, 27, 30, 16.5., think step by step
### Assistant: The variance can be calculated by first finding the mean (average) of the data, then finding the deviation of each number from the mean, squaring those deviations, adding them together, and dividing by the number of data points less one. The mean is 16.5 and the variance is 74.25. , The answer is The variance is 74.25.
