Standard Deviation

How do you calculate the mean?

• Biggest number minus the smallest number

• Find the most common number

• Order them and find the middle value

• Add all numbers up and divide by the amount of N

What is the mode of a data set?

• The most common number to appear in the data set

• The direction the data set is organized

• The middle number of the data set

• The sum of all numbers in the data set added up

What is the median of a data set?

• The most common in a data set

• The least common in a data set

• The middle value of data in numerical order

• The middle value of data when not in numerical order

How do you calculate the range of a data set?

• Smallest number added to the largest number

• Largest number minus the smallest number

• The smallest number minus the largest number

• All data added up together and then divided by N

What is standard deviation?

• The distance between the highest number and the smallest number

• The average dispersion of each data item above and below the mean

• The data set most observed

• The lowest point of data

How many steps of Standard Deviation are there?

• 4

• 5

• 6

• 7

What is step 1 of SD?

• Squaring numbers together

• calculating the mean of the data set

• Square rooting the total

• Mean minus the data set in each column

What is step 2 of SD?

• adding up the data set

• calculating the range

• subtracting the data set from the mean per column

• squaring each number in the column

What is step 3 of SD?

• squaring the answer per column from step 2

• Squaring the mean of the data column

• square rooting the sum of all squares

• subtracting the sum of all squares from the mean

What is step 4 of SD?

• Calculate the sum of all squares (add them up)

• calculate the mean of the data set

• Square root the sum of all squares

• minus the mean from the data set
