# Correlation and significant level steps

Not what you're looking for?

I have got 24 subjects I did a correlation stats on them to to find out if there is a correlation between the time spent doing online research compatred to off line research i hypothes that the more online research that is done the less off line reserch will be don. In doing the correlation I got this figure-0.117967285 I did a scattergram and it produced a line going from left down to right. My problem is i don't know if this is a correlation that is positive or negative. Now I have the minus number above I am not sure how to do someting clled a pearson's r to get a significance level of P 0.5 and once i have this P how do i express this with my minus figure above is this all you do to get a correlation and your significance wanrranted?? Pls help I encloe mey data

- "Your solution, looks excellent. I recognize things from previous chapters. I have seen the standard deviation formula you used to get 5.154. I do understand the Central Limit Theorem needs the sample size (n) to be greater than 30, we have 100. I do understand the sample mean(s) of the population will follow a normal distribution, and that CLT states the sample mean of population is the population (mean), we have 143.74. But when and WHY do we use the standard deviation formula where you got 5.154. WHEN & Why use standard deviation of the sample mean. I don't understand, why don't we simply use the "100" I understand that standard deviation is the square root of variance. I do understand that the variance is the square of the differences of each sample data value minus the mean. But somehow, why not use 100, why use standard deviation of sample mean? Please help explain."
