Question

an instructor wants to study the variance among two 30-second trials of a tennis wall volley test. what statistic will the instructor probably calculate?

Answer 1

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.

Explain the term intraclass correlation coefficient?

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.
