A statistics professor is interested in finding out if there's a relationship between the final exam scores in Statistics 102 and the final exam scores of the same students who took Statistics 101. The data are shown in the table. Stat 101 86 93 67 72 47 96 84 72 75 Part: 0/2 Part 1 of 2 Stat 102 84 95 63 73 60 90 90 62 74 (a) Use a graphing calculator to find the correlation coefficient for these data. Round to three decimal places. The correlation coefficient, rounded to three decimal places, is X S
Hello I need help with this one, calculate the Pearson product-moment correlations between at least two sets of variables in the Happiness and Engagement Dataset. Perform one correlation between two dependent variables. Perform the second correlation on an independent variable and the dependent variable OR between a different set of two dependent variables Calculate the Pearson product-moment correlations between the two sets of variables in your data set. Describe the correlations and their strength and direction.
Two variables are found to have a strong positive linear correlation. Pick the correct statement. An increase in one variable potentially causes a decrease in the other. An increase in one variable does not cause a decrease in the other. An increase in one variable does not cause an increase in the other. An increase in one variable potentially causes an increase in the other. An increase in one variable causes a decrease in the other. An increase in one variable causes an increase in the other.

Which of the following are attributes of correlation? Ocorrelation is bounded by +1 and -1 correlation is a measure of linear dependency a correlation of 0 does not mean that 2 variables are independent independent variables have 0 correlation
A correlation coefficient measures the strength of the linear relationship between two variables Select one: True False Check The closer the correlation coefficient is to -1 the more spread out the data set is. Select one: True False Check tv
Answer
After gathering data about the number of starfish and measuring the pollution in areas of the ocean you find a negative linear correlation between pollution levels and number of starfish. What can you conclude based on this information? a. There is a confounding variable that is affecting both pollution and starfish. b. As pollution rises the number of starfish falls c. That pollution is causing starfish to die, leading to the negative correlation d. That pollution is supporting starfish, leading to the negative correlation
