[amp_mcq option1=”empirical” option2=”mean” option3=”continuous” option4=”standard” correct=”option4″]<\/p>\n

The correct answer is D. standard deviation.<\/p>\n

The standard deviation is a measure of how spread out numbers are in a data set. It is calculated by taking the square root of the variance. The variance is a measure of how much variation there is from the mean.<\/p>\n

The standard deviation is often used to measure the risk of an investment or the uncertainty of a prediction. It is also used to compare the variability of two or more data sets.<\/p>\n

A. Empirical is not a measure of variability. It is a measure of the likelihood that a hypothesis is true.<\/p>\n

B. Mean is the average of a data set. It is not a measure of variability.<\/p>\n

C. Continuous is a type of data. It is not a measure of variability.<\/p>\n","protected":false},"excerpt":{"rendered":"
