Cluster sampling refers to a type of sampling method . With cluster sampling, the researcher divides the population into separate groups, called clusters. Then, a simple random sample of clusters is selected from the population. The researcher conducts his analysis on data from the sampled clusters.
If you are running around an actual football field (100 yds x 50 yds) a mile would be 5.9 laps (1 mi = 1760 yds/300 = 5.86667). A standard racetrack around a football field should be 440 yds, so 4 laps should be a mile there (1760/440 = 4).
Since 1 mile is 5,280 feet, 700 meters is less than half a mile, actually about two-fifths of a mile.Learn more about Measurements. Seven hundred meters is a little more than the length of six football fields, equal to 765.53 yards (a standard football field is 120 yards long).
