Detailed explanation-1: -Step 1: Find the mean. Step 2: Find each score’s deviation from the mean. Step 3: Square each deviation from the mean. Step 4: Find the sum of squares. Step 5: Find the variance. Step 6: Find the square root of the variance. 17-Sept-2020
Detailed explanation-2: -The larger the sample, the smaller the standard error, and the closer the sample mean approximates the population mean. Do this by dividing the standard deviation by the square root of N, the sample size.
Detailed explanation-3: -Step 1: Calculate the value of the mean, mode, or median of the given data values. Step 2: Subtract the value of the central point (here, mean) from each data point. Step 3: Now take the absolute of the values obtained in step 2. Step 4: Take the sum of all the values obtained in step 3. More items
