Mean
What is the definition of Mean?
Mean is the average of all the numbers of the data set.
What is the definition of Median?
Median is the middle number of the data set.
What is the definition of Mode?
Mode is the most common number present in a data set.
What is the definition of Range?
Range is the difference between maximum - minimum.
What does Inter Quartile Range (IQR) mean?
IQR is the first quartile subtracted from the third quartile.
How do you find the Mean of a data set?
The way you solve for the mean is by adding all of the numbers and dividing the number by the amount of numbers in the data set.
How do you find the Median of a data set?
The way you solve for the median is by counting one number at a time on both sides of the data set until both of the sides reach the same number/numbers. If there is two numbers then you add the two numbers together and find the mean of them.
How do you find the Mode of a data set?
The way you find mode is by looking at the most repeated number in a data set.
How do you find the Range of a data set?
You find the range by subtracting the minimum in the data set from the maximum in the data set and you will find the distance between the two numbers.
How do find the Inter Quartile Range (IQR) of a data set?
You find the IQR of a data set by subtracting the lower quartile from the upper quartile.
