Understanding Mean, Median, Mode, and Range

What are the four statistical measures discussed in the video?

• Algebra, geometry, calculus, trigonometry

• Length, width, height, depth

• Mean, median, mode, range

• Addition, subtraction, division, multiplication

How do you calculate the range of a set of scores?

• Arrange the scores in ascending order and find the middle value

• Find the difference between the highest and lowest scores

• Add all scores and divide by the total number of scores

• Identify the most frequently occurring score

What is the first step in calculating the range?

• Sorting the scores in ascending order

• Dividing the total by the number of scores

• Adding all the scores together

• Identifying the highest and lowest scores

What is the mean score of the class?

• 34

• 86.25

• 90

• 88

What statistical measure is used to find the average of a set?

• Range

• Median

• Mode

• Mean

How is the median found when there's an even number of scores?

• By selecting the lower of the two middle numbers

• By choosing the higher of the two middle numbers

• By taking the mean of the two middle numbers

• By counting the number of scores and dividing by two

What does the median represent in a data set?

• The average value

• The difference between the highest and lowest values

• The middle value when the data is ordered

• The most common value

What score appeared most frequently, making it the mode?

• 34

• 86.25

• 88

• 90

If there are two modes in a data set, how is it described?

• Multimodal

• Trimodal

• Unimodal

• Bimodal

Which of the following is not a measure of central tendency?

• Median

• Mean

• Range

• Mode
