Lanzetta Elem. raised 5358....round to 5,000
Lantana Mid. Sch raised 2834....round to 3,000
Atlanta High Sch. raised 4132...round to 4,000
they need 14,000...they have (5,000 + 3,000 + 4,000) = 12,000....so they will need (14,000 - 12,000) = 2,000 more....keep in mind, these are estimates...not exact answers

Answer:
Mean absolute deviation is a statistical measure of dispersion. Whisker box-plot is a graphical method of quartile based divided data
Step-by-step explanation:
Mean Absolute Deviation is a statistical measure of dispersion or variability in data. It denotes average level of deviation of observations from the central mean.
It is calculated using following formula : ( Σ | X - X' | ) ÷ N ; where X = individual observations, X' = mean, N = no. of observations
Whisker Box-plot is a graphical method of representing group of numerical data through their quartiles. This also consists line extensions from boxes, showing scatter beyond lower & upper quartile.
