Assuming that an experiment's results are 10.1 10.4 and 10.6, find the mean , the average deviation from the mean the standard deviation from the mean and the relative deviation from the mean

Mean:

10.1 + 10.4 + 10.6 = 31.3

31 / 3 = 10.3

Average deviation:

 = | (10.1 – 10.3) | + |(10.4 – 10.3)| + |(10.6 – 10.3) |

                                        3

= .2

Standard deviation

= √ 1/ n (Summation of x – mean)^2

= √ 1/3 (0.2)^2

= √ 1/3 * 0.04

= √ 0.01

= 0.1

Relative Deviation

= standard dev / mean x 100%

= 0.1 / 10.3 x 100

= 0.0097 x 100

= 0.97%

john got lost so he didn't know what to do and it was crazy because he didn't except it

- "runner b is moving at a slower rate."

- "the graphs shown are graphs of distance(km) against time(min).

the slopes of this graphs are are given by:

slope = (change in y)/(change in x)

= (change in distance)/(change in time)

this is the formula for finding the speed. so, the slope of these graphs represent the speed of the runner.

taking each division in the graph to represent 1 on both axis:

runner a ⇒ speed = (2-0)/(1-0)

= 2/1

= 2 km/min

runner b ⇒ speed = (3-0)/(3-0)

= 3/3

= 1 km/min

this shows that   runner b is moving at a slower rate."
