You take the largest number in the Set of data and then subtract it from the smallest number in that data

The mode is the most frequently appearing number in a set of data.

The coefficient of variation is a method of measuring how spread out the values in a data set are relative to the mean. It is calculated as follows: Coefficient of variation = σ / μ Where: σ = standard deviation of the data set μ = average of the data set If you want to know more about it, you can visit SilverLake Consulting which will help you calculate the coefficient of variation in spss.

To calculate the cardinality of a set you need to establish a 1-to-1 mapping from the set onto Z, the set of counting numbers.

The Casio fx-115 ES is a scientific calculator which you can use to calculate the first and third quartiles of a data set. To calculate the first and third quartiles, you first need to arrange the data set in ascending or descending order. Once the data set is arranged, you can use the following steps to calculate the first and third quartiles: Enter the data set into the calculator by pressing the Data/Matrix button. Once the data set is entered, press the STAT button and then the VARS button. Select the data set by pressing the number key that corresponds to the data set. Access the QUARTILE option by pressing the 5 key. Enter the number 1 to calculate the first quartile or enter the number 3 to calculate the third quartile. The calculator will display the first or third quartile of the data set. These steps can be used to calculate the first and third quartiles on a Casio fx-115 ES.

You calculate summary statistics: measures of the central tendency and dispersion (spread). The precise statistics would depend on the nature of the data set.

Simple! The average deviation for any data set is zero - by definition.

There is not a mean of a single number. To calculate a mean, you need a data set. The mean is given by the sum of all the data, divided by the number of pieces of data.

Mean is the average number in a set of data. To calculate mean, you add up all the numbers in a set of data and divide that sum by the amount of numbers you just added up. Example: numbers: 2, 2, 1, 3 2+2+1+3=8 How many numbers in the set? There are 4 so you divide the sum we just found by 4. 8 divided by 4=2 The mean/average of this set of data is 2.
