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).
Based upon the college track being 440 yards in length, it would take 4 trips around that oval to equal one mile. 5,280 feet = One mile 5,280 divided by 3 = 1,760 yards â¦ 1,760 yards divided by 440 = 4 (laps). Since the standard for tracks built in the last 20+ years is 400M, then you must go 9.344 meters further than 4 laps.
