Data analysis and discussion - Essay Example Thus, the responses from the participants greatly varied according to one’s opinion on a particular question. The variance and standard deviation for all the baseline variables is relatively low. For instance, a standard deviation of 0.41 for the first question implies that the data points are very close to the real mean. On the other hand, the seventh question’s standard deviation of 0.50 implies that the data points are far apart from each other; spread out in larger ranges of the variables. Looking at the correlation matrix from excel sheet 3, a number of baseline variable have a correlation of 1 whereas others have -1. For instance, variable 1 and 2, 1 and 7, 1 and 5, 1 and 6, 2 and 5, 2 and 6, 2 and 7, 3 and 8, 4 and 8, 5 and 6, 5 and 7 have a correlation of 1 which implies that they have a strong positive linear relationship. Other combinations have a strong negative linear relationship as shown in excel file. It has six questions or variables that seek to know the level of self-efficacy on students’ performance. Just like locus control, this was done on 35 participants (students) who gave different responses for the baseline variables; as shown by their means: 6.43, 6.66, 6.51, 1.97, 6.40 and 6.29 for question 1, 2, 3, 4, 5 and 6 respectively. The standard deviation for the second variable is 0.48 implying that the data points in this baseline variable are close to the mean. The highest standard deviation is 1.25 for the fourth baseline variable. This shows that the data points for this variable are far from the mean. From the excel sheet 3, the correlation coefficient differ greatly. For instance, baseline variable 1 and 2 have a correlation of 1 which shows that they have a strong positive correlation. Variable 2 and 8 have a strong negative relationship, a correlation of
