Question

calculate correlation from the following data x: 100 200 300 400 500 600 700 and y: 30 50 60 80 100 110 130
​

Answer 1

80 100,100 110, 110 130,130 140

_20_, _10_. _20_. _10_

Answer 2

Answer:

CORRELATION = 0.997

Step-by-step explanation:

TO FIND: The Correlation of the following data

Given:

  data x: 100 200 300 400 500 600 700

          y: 30 50 60 80 100 110 130

r = ∈ ($x_{i} - x bar$)($y_{i} - ybar$) /  $\sqrt{( sum of (x_{i} - x bar)^{2} (sum of (y_{i} -y bar)^{2} }$

$r$ = correlation coefficient

$x_{i}$ = values of the x-variable in a sample

$x bar$ = mean of the values of the x-variable

$y_{i}$= values of the y-variable in a sample

$ybar$ = mean of the values of the y-variable
