Question

A single value (Score) that attempts to summarize an entire list of values (scores). It can be interpreted as the "typical" value (score). Arithmetic Mean, X = sigma x/n where n is the number of scores in a list. In a frequency distribution, X = sigma (f - x)/sigma f where f is a frequency. Median: The middle score in a list when the scores in the list are arranged in order. If there is an even number or scores, n, the median is the score halfway between the (n/2)th score and the [(n/2) + 1] th score. If there is an odd number of scores, n, the median is the r th score where r is the next integer after n/2. Mode: The most frequent score in a list. Midrange: The mean of the minimum score and the maximum score in a list. Range: The difference between the maximum value in a list and the minimum value. Average Deviation Around the Mean, sigma|x - x|/n measures the average difference between individual scores in a list and the mean of the list. Sample Standard Deviation, S = squareroot z (x - x)^2/n - 1 measures the approximate difference between individual scores in a sample and the mean of the sample. The standard deviation gives essentially the same information as the average deviation from around the mean. An equivalent and easier computational formula for the sample standard deviation is S = squareroot sigma x^2 - (sigma x)^2/n/n - 1 Population Standard Deviation, sigma = squareroot sigma (x - M)^2/N where N is the population size and mu is the population mean. The sample standard deviation, S, is an estimator of sigma. The denominator of the sample standard deviation S is n - 1 instead of n. Using n as the denominator would give an estimate of sigma that is too small. Sample Variance, S^2 = sigma (x - x)^2/n - 1 = sigma^2 - (sigma)^2/n/n - 1

Explanation / Answer

No question mentioned all the information are formulas

Example: 1,2,3,4,5,6,7,8,9

Lets take 9 numbers to know the mean,median,mode

Mean = 45/9 = 5

Median = 5

Midrange = 1 + 9 /2 = 5
