Learn how to create a normal distribution curve given mean and standard deviation

The video tutorial explains the concept of standard distribution, focusing on the mean and standard deviation. It covers how to calculate standard deviations and the percentages of data within each deviation. The tutorial emphasizes the importance of understanding these concepts for tests and provides a detailed breakdown of the first, second, and third standard deviations, including their respective percentages.

What is the position of the mean in a standard distribution?

• At the end

• In the middle

• At the beginning

• Randomly placed

How do you calculate the first standard deviation in a normal distribution?

• By dividing the mean by the standard deviation

• By subtracting the mean from the standard deviation

• By adding and subtracting the standard deviation from the mean

• By multiplying the mean by the standard deviation

What percentage of data falls within the first standard deviation in a normal distribution?

• 99.7%

• 95%

• 68%

• 50%

What is the total percentage of data within two standard deviations in a normal distribution?

• 68%

• 100%

• 95%

• 99.7%

What percentage of data is accounted for within three standard deviations in a normal distribution?

• 99.7%

• 68%

• 95%

• 100%
