Exploring Mean, Median, Mode, and Range

What is the first step in creating a reference sheet for statistics?

• Write down the data set

• List all the statistical formulas

• Divide the paper into four sections

• Gather statistical tools

What material is needed to start creating the reference sheet for statistics?

• A piece of blank paper

• A computer

• A calculator

• A textbook

What is the formula to calculate the mean of a data set?

• Find the middle value after sorting the data

• Identify the most frequently occurring number

• Divide the sum of all values by the number of values

• Subtract the smallest value from the largest

Which statistical measure would be most affected by an outlier in the data?

• Mean

• Median

• Mode

• Range

How do you find the median in a dataset with an even number of elements?

• Pick the most frequent number

• Average the two middle numbers

• Subtract the smallest from the largest number

• Choose the smallest number

What is required to calculate the median of a dataset?

• Calculating the total sum of all values

• Ordering the values from least to greatest

• Finding the most frequent value

• None of the above

What does the mode represent in a dataset?

• The middle value

• The most frequently occurring value

• The difference between the highest and lowest values

• The average of all values

If a dataset's mode is 93, what does that imply?

• 93 is the average of all values

• 93 appears most frequently

• 93 is the middle value

• 93 is the range of the dataset

What does the range tell us about a dataset?

• The most common value

• The average value

• The spread between the highest and lowest values

• How consistent the data is

In a dataset with grades 73, 84, 87, 89, 93, 93, what is the range?

• 10

• 73

• 93

• 20
