What are the measures of center discussed in the video?

• Mean, Median, Variance, and Standard Deviation

• Average, Median, Mode, and Distribution

• Mean, Midpoint, Mode, and Range

• Mean, Median, Mode, and Range

How do you calculate the mean of a data set?

• Subtract the smallest number from the largest number

• Add all numbers and divide by the count of numbers

• Arrange numbers in ascending order and pick the middle one

• Identify the number that appears most frequently

What is the median of the data set 35, 55, 50, 20, and 45?

• 50

• 45

• 35

• 55

What should be included when calculating the mean?

• Only positive numbers

• Only non-zero numbers

• All numbers, including zero

• The highest and lowest numbers only

If a data set has two numbers in the middle, how do you find the median?

• There is no median

• Choose the smaller number

• Calculate the mean of the two numbers

• Choose the larger number

What indicates the mode in a data set?

• The most frequent number

• The least frequent number

• The average of all numbers

• The difference between the highest and lowest numbers

What is the mode of the data set 50, 65, 90, 50, 75, 65, and 80?

• 75

• There is no mode

• 50 and 65

• 90

What does the range measure in a data set?

• The middle value

• The most frequent value

• The variation between values

• The average value

How do you find the range of a set of numbers?

• Add the smallest and largest numbers

• Identify the most frequent number

• Divide the sum of all numbers by their count

• Subtract the smallest number from the largest number

Which of the following is a measure of variation?

• Range

• Mean

• Median

• Mode
