Determine if the following statement is true or false. A correlation coefficient close to 1 is evidence of a cause-and-effect relationship between the two variables. The statement is true O A. False. Only a correlation coefficient close to 0 indicates a cause-and-effect relationship between the two variables O B. False. A correlation coefficient should not be interpreted as a cause-and-effect relationship O c. True, but only if all the conditions for correlation are met. False. A correla.on coefficient of 1...

QUESTION 1 There are different types of correlation one can use based on the types of variables being examined. When conducting an analysis, when do you need to use Spearman’s rho instead of Pearson’s r? When the data are nominal or ordinal. When the data are ratio or interval. When the data are random. Spearman's rho should never be used for correlations. 10 points QUESTION 2 True/False. If you found a strong positive correlation between the number of hours...
