Question

Paper Helicopter Experiment Materials needed: For each pair of students, template for helicopter, paper clip, 4 feet of string, ruler, paper to mark target. Template can be found at: Overview: A helicopter will be dropped from waist height at a target. The linear distance of the center of the helicopter shaft to the target is measured. A paper clip is attached to the shaft and the experiment is repeated Specific instructions: Determine who will be the person (launcher) dropping the helicopter. The launcher creates a plumb line by attaching the paper clip to the string. The launcher holds the plumb line at waist height from where the helicopter will be dropped while the other partner (measurer) marks the target on the paper as the point vertically underneath the launch point. Launcher drops the helicopter and remains in place while the measurer records the distance the center of the shaft is from the target. For the second launch the paper clip is attached to the shaft. The launcher drops the helicopter, the measurer records the distance. 1. Drop each of your helicopters 10 times. Record the distance to the closest half-inch from the center of the helicopter's shaft to the target Helicopter1 type With paper clip Without paper clip Calculate each measure of central tendency and dispersion using your graphing calculator. Helicopter Mean 01 Median Q3 Standard deviation With paper clip Without paper cllp Overall for the 20 drops

Answer 1

1. Measurements of distance in inches:

Helicopter	1	2	3	4	5	6	7	8	9	10
With paper clip	28.5	30	32	30	23	33.5	29.5	31.5	20.5	25.5
Without paper clip	22.5	10	16.5	12	14	11.5	17.5	19.5	18	18

Helicopter type	Mean($\mu$​​​​​​) ​​​​​​	Std.deviation($\sigma$) ​​​​​	Q1	Median	Q3
With paper clip	28.4	3.94	25.5	29.75	31.5
Without paper clip	15.95	3.76	12	17	18
Overall for 20 the drops	22.175	7.32	17	21.5	29.5
