Step-by-step explanation:
grade?
The given line
4x + y = 5
The slope of the given line is -4
Find the slope of perpendicular line
m₁ × m₂ = -1
-4 × m₂ = -1
m₂ = -1/-4
m₂ = 1/4
Find the equation of perpendicular line
y - y₁ = m(x - x₁)
y - 9 = 1/4(x - 8)
y - 9 = (1/4) x - 2
y = (1/4)x - 2 + 9
y = (1/4)x + 7
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.
