1. Read the description of a study and answer the three questions below In the past it was often assumed that males outperform females in mathematics achievement. In this study, researchers looked at a group of male and female high-school students, and measured their mathematics computation skills using a standard test that gives a score ranging from 0 to 100. Test results: t (28) = 2.55, p = .055

i.The measurement for the variable 'gender' is: (delete or cross over the incorrect answers) nominal ordinal scale ii) The measurement for the variable 'math computation' is: nominal ordinal scale iii) The results are: significant not significant

2. Look at the SPSS output below and say which test this is, what are independent and dependent variables, and how would report this result .
