Exploring Mean, Median, Mode, and Range Concepts

Miss Wendell addresses a technical issue with a previous video and provides a new tutorial on basic statistical concepts such as mean, median, mode, range, and outliers. She explains how to solve 'work backwards' problems with detailed examples, including a step-by-step solution using bowling scores. The video concludes with additional examples and practice problems for students to work on, with an invitation to seek help if needed.

What statistical measure is used when you need to find a central value in a set of numbers?

• Median

• Mean

• Range

• Mode

If the average score needed is 91, and the sum of scores is 364, how many games were played?

• 4 games

• 3 games

• 5 games

• 6 games

To find a missing score for an average of 91, what operation is performed after summing known scores?

• Multiplication

• Subtraction

• Division

• Addition

What is the missing score Sally needs to achieve an average of 91?

• 91

• 89

• 93

• 87

In the context of finding a mean, what does working backwards involve?

• Adding then dividing

• Subtracting then adding

• Dividing then multiplying

• Multiplying then subtracting

What is the median of a dataset if the numbers are 17, 19, and 21?

• 21

• 19

• 18

• 17

How do you determine the missing number in a dataset to achieve a median of 18?

• Find the average of all numbers

• Identify the middle value after sorting

• Calculate the mode of the dataset

• Use the range of the dataset

What is the correct approach to find a missing number that ensures the median is 18?

• Guess and check different numbers

• Place the numbers in order and find the middle

• Subtract the highest from the lowest

• Add all numbers and divide by total count

If the median must be 81, and the numbers are 70, 77, 80, 82, 87, 88, what could be the missing number?

• 86

• 81

• 83

• 85
