Basically, we multiply the numbers altogether and take the nth root of the multiplied numbers, where n is the total number of data values. For example: for a given set of two numbers such as 3 and 1, the geometric mean is equal to √ (3×1) = √3 = 1.732. In other words, the geometric mean is defined as the nth root of the product of n numbers.Mean and standard deviation problems along with their solutions at the bottom of the page are presented.

Here the Greek letter μ the mean and σ is the standard deviation. The standard normal distribution is a special normal distribution. It has a mean of 0 and its standard deviation is equal to 1. Unit 1 Analyzing categorical data Unit 2 Displaying and comparin Solution: The calculated arithmetic mean of 40 numbers is 38. Hence, the sum of these numbers = (38 × 40) = 1520. Thus, the actual sum of these numbers = [1520 – (Incorrect value) + (correct value)] Correct Mean = 1520 – 36 + 56. Correct Mean = 1540. Hence, the correct mean of the given numbers = 1540/40 = 38.5. 5.And the correlation coefficient is the degree in which the change in a set of variables is related.
