Understanding Mean, Median, Mode, and Range

What statistical measures help us understand data better?

• Algebra, Geometry, Calculus

• Addition, Subtraction, Multiplication, Division

• Charts, Graphs, Tables

• Mean, Median, Mode, Range

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

• Add all numbers and divide by the total count

• Find the middle number

• Subtract the smallest from the largest

• Identify the most frequent number

What is the first step in calculating the mean?

• Subtracting the smallest number from the largest

• Adding all numbers together

• Finding the most frequent number

• Ordering the data from least to greatest

What is the median of a data set with an odd number of elements?

• The average of all numbers

• The middle number when ordered

• The most frequent number

• The difference between highest and lowest

If a data set has an even number of elements, how is the median found?

• Most frequent number

• Average of two middle numbers

• Sum of all numbers

• Middle number

What is the median of the data set if the number of elements is even?

• The sum of two middle numbers divided by two

• The difference between the highest and lowest numbers

• The number right in the middle

• The most frequent number

What does the mode represent in a data set?

• Average of all numbers

• Most frequent number

• Middle value

• Difference between highest and lowest

Can a data set have more than one mode?

• Yes, if multiple numbers appear most frequently

• Yes, if the numbers are all the same

• No, mode is always the largest number

• No, only one number can be the mode

How do you calculate the range of a data set?

• Identify the least frequent number

• Find the average of all numbers

• Subtract the smallest number from the largest

• Add the smallest and largest numbers

What does the range tell us about a data set?

• Which number appears most

• How many data points there are

• How spread out the data is

• The average value of the data
