47
Q

VOC is also known as…

A

…the requirements of the customer

48
Q

What is the normal distribution?

A

a probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean. In graph form, normal distribution will appear as a bell curve.

49
Q

What is the mean and how to calculate it?

A

The average value of numbers in a set. Find the mean by adding up all numbers and dividing it by the amount of numbers

50
Q

What is the median and how to calculate it?

A

The number in the middle. Find the median by putting the number in order from smallest to largest and finding the number that is in the middle.

51
Q

What is the mode and how to calculate it?

A

The number that occurs the most frequent of all numbers. Find the mode by putting the numbers in order from smallest to largest and look for the number that occurs the most.

52
Q

What is the variance?

A

It is calculated by taking the average of squared deviations from the mean. Variance tells you the degree of spread in your data set. The more spread the data, the larger the variance is in relation to the mean.

53
Q

What is the standard deviation?

A

a measure of the amount of variation or dispersion of a set of values. A low standard deviation indicates that the values tend to be close to the mean (also called the expected value) of the set, while a high standard deviation indicates that the values are spread out over a wider range.

54
Q

How to calculate the interquartile range?

A
