Question
Analyze the following output from a Pearson’s correlation coefficient test:
Pearson's product-moment correlation data: age and bmi t = 1.8726, df = 198, p-value = 0.06259 alternative hypothesis: true correlation is not equal to 0 95 percent confidence interval: -0.006948632 0.265795808 sample estimates: cor 0.1319196
Based on the p value, select the most appropriate conclusion. Assume a significance level of 0.05.
A. There is a negative correlation between age and BMI.
B. There is a positive correlation between age and BMI.
C. There is no correlation between age and BMI.
D. There may be a correlation between age and BMI, but it is not statistically significant.
Explanation / Answer
Ans:
As,p-value=0.06259>0.05,we fail to reject null hypothesis.(i.e true correlation equal to 0)
So,we can conclude that true correlation is equal to 0.
Hence,option C is correct.
There is no correlation between age and BMI.
