When finding the median with an even amount of data, I need to

• find the number in the middle

• add the two data values together, then divide by 2

• add all the data values together, then divide by the amount of data values

• find the number that repeats the most

• add all the data values together, then divide by 2

Describe the difference between the calculation of population standard deviation and that of sample standard deviation.

Let N be the number of data entries in a population and n be the number of data entries in a sample data set. Choose the correct answer below.

• When calculating the population standard​ deviation, the sum of the squared deviation is divided by​ N, then the square root of the result is taken. When calculating the sample standard​ deviation, the sum of the squared deviations is divided by n −​1, then the square root of the result is taken.

• When calculating the population standard​ deviation, the sum of the squared deviation is divided by the number of​ entries, N −​1, then the square root of the result is taken. When calculating the sample standard​ deviation, the sum of the squared deviations is divided by​ n, then the square root of the result is taken.

What does the value N​ mean?

• The mean of the population data.

• The difference between all the values in the population data set.

• The number of values in the population data set.

• The range of the population data.

What does the value μ ​mean?

• The difference between all the values in the population data set.

• The mean of the population data set.

• The most common value in the population data set.

• The range of the population data set.
