What does the IQR tell you about a data set?
It gives a measure of the spread of the data.
What is the approximate length of a side of the field if the area is 479 ft2 and Why?
You can't tell. There are an infinite number of sets of different dimensions that the field could have, all with the same area. The area doesn't tell you the length or width.
Difference between activity diagram and dfd?
In data flow diagrams, the lines between "boxes" represent data that flows between components of a system. Because these only show the flow of data, they do not give an indication of sequencing.In activity diagrams, those lines are simply transitions between activities and do not represent data flow at all. They more represent the sequencing of activities and decisions. You can tell from these what order things happen in.
What does the mean tell us about the data?
the mean tells us a about the average of the data. it's what most people received averaged up. Ex. 19, 5, 3, 20, 11,and 15. then you add them up the addition answer is 73. then you divide 73 by the amount of numbers in the data, 6. 73/6=12.1. this tells us that roughly, the average of these 6 people is 12.1. hope that helps.
