A local city is considering building a new train to alleviate the heavy traffic on its highways. To find out how many people would make use of this new train, a government worker went out and interviewed a random sample of commuters
The following are the number of
miles driven each week by 10 people who said that they would use the train instead of
driving to work:
150 750 300 425 175 600 450 250 900 275
Calculate the (a) range, (b) inter-quartile range, and (c) variance and standard deviation.
What would be an ideal response?
a.
900 150

Field experiments allow greater control over conditions than do laboratory experiments. 5. Non-equivalent control group designs designate experimental and comparison groups before the treatment occurs.
