AlexFokin [52]

The tennis wall volley test has two 30-second trials, and a teacher is interested in analyzing the variation between them. The instructor will most likely determine the "intraclass correlation coefficient" statistic.

<h3>Explain the term intraclass correlation coefficient?</h3>

An indicator of the validity of the ratings for clusters is the intraclass correlation coefficient, abbreviated ICC.

  • Data that is grouped together is referred to as a cluster. Instead than comparing two independent classes of data, ICC is used to detect correlations within a specific class of data.
  • As was already noted, Pearson's r is the most often utilized correlation coefficient.
  • When there are just one or two significant pairs from just one or two raters, Pearson's correlation coefficient is typically employed to measure inter-rater reliability.
  • However, this intraclass correlation coefficient ought to be utilized if there are more pairs.

it was estimated that the united states would need 6200 more veterinarians in 2012. The percent error was 10%. if the estimate w
Margaret [11]
5580 veterinarians were actually needed. 

To find this you must find what is 10% of 6200. 

In math, of = multiplication. 

So you multiply 10% and 6200. In order to do so, you must turn the percentage into a decimal or fraction. So 0.1 x 6200

That should get you 620. However, that IS NOT your final answer, since 620 is only 10% of the total, not the amount needed.

To get the actual amount of veterinarians, you subtract 620 from 6200, and should get 5580, the final answer.
