WebStandard deviation function. To use this function, choose Calc > Calculator. Measures the dispersion (how spread out the data are) about the mean. While the range estimates the spread of the data by subtracting the minimum value from the maximum value, the standard deviation approximately estimates the "average" distance of the individual ... WebThe steps for calculating the sample standard deviation are: Calculate the mean (simple average of the numbers). For each number: subtract the mean and square the obtained result. Sum up all of the squared results. Divide this sum by one less than the total number of data points (n - 1). This will give us the sample variance.
WebApr 21, 2024 · The variance and standard deviation are important in statistics, because they serve as the basis for other types of statistical calculations. For example, the standard deviation is necessary for converting test scores into Z-scores. The variance and standard deviation also play an important role when conducting statistical tests such as t-tests.
WebExample 1: For sample variance. Find the standard deviation of the given sample: 30, 20, 28, 24, 11, 17. Solution. Step 1: Calculate the mean value of sample data: N = 6.
