Measures of Central Tendency

The video tutorial covers the concepts of mean, median, and mode, explaining each with examples. It begins with an introduction to these statistical measures, followed by a detailed explanation of the mean, including how to calculate it and its significance. The tutorial then explores how to calculate GPA using weighted averages. The median is discussed next, highlighting its importance in representing data without being affected by outliers. Finally, the mode is explained, focusing on its role in identifying the most frequently occurring data points.

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

• Median, Range, Mode

• Mean, Median, Range

• Mean, Range, Mode

• Mean, Median, Mode

How is the mean calculated?

• By finding the middle value

• By identifying the most frequent value

• By adding all values and dividing by the number of values

• By subtracting the smallest value from the largest

In the basketball score example, what was the mean score?

• 85.4

• 82.3

• 90.2

• 87.5

How is the median determined in a data set?

• By finding the most frequent value

• By calculating the average of all values

• By identifying the middle value after ordering the data

• By subtracting the smallest value from the largest

What does GPA stand for?

• General Performance Average

• Grade Point Average

• Great Performance Average

• Grade Performance Assessment

Why might the median be preferred over the mean in some cases?

• It is easier to calculate

• It is not affected by outliers

• It always gives a higher value

• It is more commonly used

What is the mode in a data set?

• The difference between the highest and lowest values

• The most frequently occurring value

• The middle value

• The average of all values

What does it mean if a distribution is bimodal?

• It has two medians

• It has two different means

• It has two ranges

• It has two modes
