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).
How many laps = one mile on your indoor track. Discussion in 'Running at WDW' started by DisneyRunner, Jul 14, 2010. With a number of people running indoors due to heat and humidity, this is an interesting question. Running the ouside lane at the my YMCA, 11 laps equals one mile. Click to expand... I run a good bit on the indoor track at the Y in downtown Birmingham. I usually run the inside lane, where 10 1/2 laps equals one mile. At the other Y I go to, 17 laps equals one mile. That gets a bit tedious.
