Solved A Researcher Calculates The Pearson Correlation | Chegg.com A researcher calculates the pearson correlation coefficient to examine the correlation between number of times a person had a sunburn and minutes outside during the day. below is the output. choose the correct interpretation. Explanation: pearson correlation coefficient is used to measure the degree of correlation between two variables.

Solved A Researcher Calculates The Pearson Correlation | Chegg.com You can use the pearson () function to calculate the pearson correlation coefficient in excel. if your variables are in columns a and b, then click any blank cell and type “pearson (a:a,b:b)”. Given that the pearson correlation is 1, this indicates a perfect negative linear relationship. in other words, as one variable increases, the other variable decreases at a consistent rate. There are 3 steps to solve this one. prepare your data in pairs of scores and compute the key quantities: the sum of the scores, the sum of the scores, the sum of the product of paired scores, the sum of squared scores, and the sum of squared scores. The researcher obtained a value of r = − 1.52, which is outside the valid range for the pearson correlation coefficient. therefore, the result of r = − 1.52 is an error or a miscalculation, as it is not within the valid range of 1 to 1 for the pearson correlation coefficient.

Our expert help has broken down your problem into an easy to learn solution you can count on. question: a researcher collects data from 18 people and calculates a pearson correlation of r = .42. assuming alpha = .05 (two tailed), the researcher would make the decision to . A pearson correlation coefficient of 0.72 indicates a moderate to strong positive correlation between holiday expenditure and another variable. this suggests that as holiday expenditure increases, the other variable also tends to increase. A pearson correlation of 1 indicates a perfect negative linear relationship between the variables this means that as one variable increases, the other decreases at a constant rate. Calculate pearson's correlation coefficient from the data given below (you can use r or calculator). find p value to test hypothesis that population correlation coefficient is significant.
