A common concern for students (and teachers) is the assignment of grades for essays or term papers. Because there are no absolut

e right or wrong answers, these grades must be based on a judgment of quality. To demonstrate that these judgments actually are reliable, an English instructor asked a colleague to rank-order a set if term papers. The ranks and the instructor's grades for these papers are as follows:
Rank: 1, 2, 3, 4, 5, 6,7,8,9,10, 11
Grade: A,B, A, B, B, C,D, C,C,D, E
A) Compute the Spearman correlation for these data.
B) Is there a significant correlation between the two instructors' judgments of the papers. Use a two tailed test with alpha = 0.05

The table shows the number of cups of water required when cooking different amounts of rice.
Harman [31]

<u>Answer-</u>

<em>The amount of water is the dependent value.</em>

<u>Solution-</u>

Plotting the graph from the given data points, it comes out to be a straight line with positive slope. So, both the variables i.e amount of rice and amount of water are in a linear relationship. They are directly proportional to each other.

As the amount of rice increases, the water needed to cook the rice also increases. Plotting a graph taking amount of rice in abscissa and amount of water in ordinate, a straight line was obtained.

Here, amount of rice is the independent variable and amount of water is dependent variable as it depends on the amount of rice.
