Question 627332
80.83,91,92,94
Mean= (add all) / (how many there is)
440/5= 88
Median= the center of the data in order from least to greatest
In this case it is 91
Mode= What number appears most often in a set of data
None

80,82,83,91,92,94
Mean= 522/6= 87
Median= The median is between 83 and 91 so what you do is add them up and divide by 2. 83+91=174   174/2= 87
Mode= None

Therefore the mean decreased by one and the median is decreased by 4 and the there still is no mode.
