Miss Watson runs a distance of 200 meters in 25 seconds
work out the average speed of miss Watson in meters per second

8m/s

Step-by-step explanation:

Average speed = distance/time taken

So

200m/25s

an advantage of the standard deviation is that it increases as the dispersion of the data increases. e. the interquartile range is preferred when the data are not skewed or no have outliers. an advantage of the standard deviation is that it uses all the observations in its computation.
