Consider a correlation coefficient of .095 between variables A and B. The correlation coefficient was calculated from a sample of 1100 respondents and is statistically significant, p < .0001. Consider a correlation coefficient of .891 between variables C and D. The correlation coefficient was calculated from a sample of 15 observations and is statistically nonsignificant, p > .10. So, when should marketing analysts consider a correlation strong enough to even consider given the issue raised above?

For the following scenario, identify whether a correlation coefficient can be accurately calculated and interpreted – if there is an issue, indicate the most relevant reason why we should be cautious when interpreting the correlation coefficient. You can assume all measures are quantitative. Shawna is interested in seeing whether there is a relationship between a person’s openness to new experiences and their creativity. She collects a random sample from her community and records their scores on two questionnaires that measure...

4) The correlation coefficient r is a sample statistic. What does it tell us about the value of the population correlation coefficient ρ (Greek letter rho)? You do not know how to build the formal structure of hypothesis tests of ρ yet. However, there is a quick way to determine if the sample evidence based on ρ is strong enough to conclude that there is some population correlation between the variables. In other words, we can use the value of...

Suppose we have the correlation coefficient for the relationship between two variables, A and B. Determine whether each of the following statement is true or false. (a) The variables A and B are categorical. (b) The correlation coefficient tells us whether A or B is the explanatory variable. (c) If the correlation coefficient is positive, then lower values of variable A tend to correspond to lower values of variable B. (d) If the correlation between A and B is r...
