Exploring the Mean in Measures of Central Tendency

The video tutorial introduces basic statistical terms such as mode, range, and median. It then provides a detailed explanation of how to calculate the mean of a set of numbers. The process involves summing the numbers and dividing by the count of numbers to find the average.

What is the mode in a set of data?

• The most frequently occurring number

• The average of all numbers

• The middle value when data is ordered

• The difference between the highest and lowest values

How do you find the range of a dataset?

• Subtract the smallest number from the largest number

• Add all numbers and divide by the count of numbers

• Identify the most frequently occurring number

• Arrange the numbers and pick the middle one

What is the median in a dataset?

• The sum of all numbers divided by their count

• The difference between the highest and lowest values

• The most common number

• The middle value in an ordered set

How do you calculate the mean of the numbers 2, 2, 6, 7, and 8?

• Identify the number that appears most often

• Subtract the smallest number from the largest

• Find the middle number after sorting

• Add all numbers and divide by 5

What is the sum of the numbers 2, 2, 6, 7, and 8?

• 25

• 23

• 20

• 22

If you divide 25 by 5, what is the result?

• 6

• 5

• 4.5

• 5.5

What does the mean represent in a set of numbers?

• The average value

• The difference between the highest and lowest values

• The middle value

• The most frequent value
