Measures of Central Tendency

What are mean, median, and mode collectively known as?

• Measures of central tendency

• Statistical distributions

• Probability metrics

• Data set outliers

How do you calculate the mean of a dataset?

• Add all numbers and divide by the count of numbers

• Subtract the smallest value from the largest

• Identify the most frequently occurring number

• Find the middle value after sorting the data

What does the mean represent in a dataset?

• The most common value

• The numerical average

• The difference between the highest and lowest values

• The middle value

What is the median of a dataset?

• The difference between the highest and lowest values

• The most frequently occurring number

• The average of all numbers

• The middle value when the data is in order

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

• Equal to the median

• Equal to the mean

• The dataset has no mode

• The smallest number

Can a dataset have more than one mode?

• Yes, if multiple numbers occur most frequently

• No, a dataset can only have one mode

• Yes, but only if the dataset has an even number of values

• No, modes are not applicable to datasets

How is the range of a dataset determined?

• By finding the average of the dataset

• By counting the number of values

• By subtracting the smallest value from the largest

• By identifying the middle value

What indicates a dataset's variability?

• Mode

• Median

• Mean

• Range

What is the median of 0, 1, 2, 6, 6?

• 2
