The video tutorial covers measures of central tendency, including mean, median, and mode. It explains how to calculate each measure and apply them to solve problems. The tutorial also discusses how to analyze score distributions using these measures, emphasizing the differences between them.

What are the three measures of central tendency discussed in the video?

• Median, Range, Mode

• Mean, Median, Range

• Mean, Median, Mode

• Mean, Range, Mode

How do you calculate the mean of a data set?

• Add all numbers and divide by the number of numbers

• Find the middle number

• Identify the most frequent number

• Subtract the smallest number from the largest

What is the median in a data set?

• The average of all numbers

• The middle value when numbers are ordered

• The difference between the highest and lowest values

• The most frequently occurring number

Which measure of central tendency is identified by finding the most frequent number?

• Mean

• Median

• Mode

• Range

In the problem discussed, why was mode ruled out?

• All numbers appeared only once

• The median was already calculated

• The mean was already calculated

• The numbers were not in order

How can you verify if a number is the median?

• See if it appears most frequently

• Check if it is the average

• Calculate the range

• Ensure it is the middle value

What is the process to find the median in an even set of numbers?

• Average the two middle numbers

• Choose the middle number

• Subtract the smallest from the largest

• Find the most frequent number

Which measure of central tendency involves division?

• Range

• Mean

• Median

• Mode

In the student test scores problem, what was the mode?

• 42.5

• 72

• 44

• 41

In the distribution of scores, which statement is true?

• Mean and median are the same

• Mean is less than mode

• Mean is less than median

• Mean is greater than median
