Then calculate the volume of a right circular eylinder, using: nd²h V = m?h = 4 where d is the mean diameter and h is the mean height. Error Analysis Note that to calculate the percent error in volume, you must add twice the percent error in the diameter to the percent error in height, that is: % error in V = 2 x % error in diameter + % error in height To find the standard deviation associated with the volume you must multiply the percent error in the volume times the mean value of the volume and divide the result by 100, that is, %errorx X 100 Also, it is best to use scientific notation to express your results in the form: V = 4.01±0.05x104 m³ (1%).

Inverse Normal Distribution
The method used for finding the corresponding z-critical value in a normal distribution using the known probability is said to be an inverse normal distribution. The inverse normal distribution is a continuous probability distribution with a family of two parameters.
Mean, Median, Mode
It is a descriptive summary of a data set. It can be defined by using some of the measures. The central tendencies do not provide information regarding individual data from the dataset. However, they give a summary of the data set. The central tendency or measure of central tendency is a central or typical value for a probability distribution.
Z-Scores
A z-score is a unit of measurement used in statistics to describe the position of a raw score in terms of its distance from the mean, measured with reference to standard deviation from the mean. Z-scores are useful in statistics because they allow comparison between two scores that belong to different normal distributions.
with given data I need help to find the standard deviation on both charts, and finding the volume of cyilender with the error % and standard deviation at the bottom of page, thank you!
