Exploring Mean, Median, Mode, and Range

What is the mode of a set of numbers?

• The difference between the highest and lowest numbers

• The number that appears most frequently

• The middle number when sorted

• The average of all numbers

How do you calculate the mean of a set of numbers?

• Identify the middle number in a sorted list

• Find the number that appears most often

• Subtract the smallest number from the largest

• Add all numbers and divide by the count of numbers

What is the median in a sorted set of numbers?

• The average value of all numbers

• The most frequently occurring number

• The number in the middle of the dataset

• The difference between the highest and lowest values

How do you find the median if the dataset has an even number of elements?

• Use the most frequent number

• Average the two middle numbers

• Pick any middle number

• Subtract the smallest from the largest number

What does the range of a dataset tell you?

• The total count of all numbers

• The most common number

• The difference between the highest and lowest values

• The middle value of the dataset

How is the lower quartile determined in a dataset?

• It is the median of the lower half of the dataset

• It is the highest number in the dataset

• It is the lowest number in the dataset

• It is the average of all numbers

What is the upper quartile in a dataset?

• The median of the upper half of the dataset

• The lowest number in the dataset

• The average of all numbers

• The highest number in the dataset

What is the interquartile range?

• The range between the first and third quartiles

• The average of all numbers

• The mode of the dataset

• The median of the dataset

What is the correct order to find the interquartile range?

• Add all numbers together and divide by the total number of numbers

• Subtract the lowest value from the highest value

• Find the mode, then the mean, then the median

• Sort the data, find the median, then find the medians of the two halves

What should you do first when given a new set of unsorted numbers?

• Calculate the mean

• Sort the numbers in ascending order

• Find the range

• Identify the mode
