I want to calculate how significant a correlation is
I use this code for the correlation. How can I see if this correlation is statistically significant?
I guess I can use this code, but I have to add something.
cor(data$variable1,data$variable2)
x <- c(6,7,8,17,12,16)
y <- c(33.46,50.68,87.92, 98.84, 63.6, 107.3)
cor(x, y, method = c("pearson"))
cor.test(x, y, method=c("pearson"))
The result is a 2 tailed p value. Take half of it. If the half is less than your significance level alpha, then the null hypothesis of no correlation is rejected/
cor.test(data$variable1,data$variable2)
should do the job too, right?
