Question

Calculate correlation and probable error

Using the following formula

coefficient of correlation (r).

? = ?(∑??)−(∑?)(∑?) √[?(∑? 2)−(∑?) 2][?(∑?2)−(∑?) 2]

Number of families(x)	2	2	2
Number of sites(n)	1	1	1
Temperature(y) in autumn	24.1	19	27

Definition Definition Relationship between two independent variables. A correlation tells the degree to which variables move in relation to each other. When two sets of data are related to each other, there is a correlation between them.

Q1. A psychologist conducted a study on the relationship between introversion and shyness. The values are results for scales of introversion and shyness. High positive scores on each scale indicate high introversion or shyness; and high negative scores indicate low introversion or shyness. Data collected from 10 people as follows: Introversion 4 -7 -1 0 6 7 -4 -9 -5 8 Shyness 11 -7 -1 -3 0 7 -1 -8 -1 5 a) Compute the correlation coefficient relating introversion and shyness scores. b) Find the regression equation which predicts introversion from shyness. c) What introversion score would you predict from a shyness score of 7?
