Understanding Data Sets

What is a data set?

• A single number

• A collection of numbers related to a specific topic

• A mathematical operation

• A type of video game

In the context of data sets, what does the term 'mean' refer to?

• The smallest number in the set

• The largest number in the set

• The average of the numbers in the set

• The most frequently occurring number

How do you find the median in a data set with an odd number of elements?

• Add all numbers and divide by the count

• Find the middle number after sorting the set

• Identify the most frequent number

• Subtract the smallest number from the largest

What should you do if a data set has two middle numbers when finding the median?

• Choose the smaller number

• Ignore one of the numbers

• Choose the larger number

• Find the average of the two middle numbers

What is the median of the data set: 1, 1, 2, 3, 4, 5?

• 2

• 3

• 3.5

• 2.5

What does the mode of a data set represent?

• The difference between the largest and smallest numbers

• The number that appears most frequently

• The middle number

• The average of the numbers

If a data set has no repeating numbers, what is the mode?

• The average of all numbers

• The smallest number

• The largest number

• There is no mode

How is the range of a data set calculated?

• By identifying the most frequent number

• By subtracting the smallest number from the largest

• By finding the average

• By adding all numbers together

What is the range of the data set: 3, 5, 1, 2, 4?

• 5

• 4

• 3

• 2

Which of the following is NOT a part of a data set?

• Mode

• Matrix

• Mean

• Median
