WebStep 1: Firstly, calculate the mean (x̄) by adding up all the data points present in the dataset. Then divide them by the number of data points. Mean (x̄) = (46 + 69 + 32 + 60 + 52 + 41) / 6 = 50. Step 2: Now subtract the mean value from each data point to obtain the individual deviation from the mean. As the mean is 50. WebBut, if we a large set of data for calculation or we want to get an accurate result, then we should use the covariance calculator.
