● 3x^2 - 10 = 0
Add 10 to both sides
● 3x^2 - 10 + 10 = 10
● 3x^2 = 10
Divide both sides by 3
● 3x^2/3 = 10/3
● x^2 = 10/3
● x = √( 10/3 ) or x = - √( 10/3 )
● √(10/3) + (-√(10/3)) = 0
● √(10/3) × -√(10/3) = -10/3

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.
