Find the value of the linear correlation coefficient r
-Two different tests are designed to measure employee productivity and dexterity. Several employees are randomly selected and tested with these results. $\begin{array}{cc|c|c|c|c|c|c|c|c|c}
\text { Productivity } & 23 & 25 & 28 & 21 & 21 & 25 & 26 & 30 & 34 & 36 \
\hline \text { Dexterity } & 49 & 53 & 59 & 42 & 47 & 53 & 55 & 63 & 67 & 75
\end{array}$
A) $0.471$
B) $0.115$
C) $- 0.280$
D) $0.986$

Quizplus · Accepted Answer

The linear correlation coefficient $r$ measures the strength and direction of a linear relationship between two variables. Given the data for productivity and dexterity, calculating $r$ involves a statistical formula that considers the means, standard deviations, and covariance of these two sets of data. The calculation, which is not shown here, results in a value close to $0.986$, indicating a very strong positive linear relationship between employee productivity and dexterity.
