The above table shows the results of t test run to examine the relationship between two conditions namely scared straight and no intervention. The results suggest that there is no significant relationship between the two groups under study. This is depicted by the value under the Sig (2 tailed) in the last column of the above table. The level of significance is assumed to be 0.05 and the value 0.495 is greater than this value. A paired sample t-test is used to show that the tests have been run on the same subjects regarding weights. This is also shown by the identities of the respondents given in the original data. When subjects are the same, we use a paired sample t test CITATION HAD12 \l 1033 (H.A.David & L.Gunnink, 2012).

The above table shows the correlation between the weight and motivational interviewing. The correlation coefficient is 0.272 which shows a weak positive correlation between the two variables. This means that both variables will move in the same direction to each other CITATION Jam03 \l 1033 (Hemphill, 2003).
