An education researcher was interested in studying whether male students who take classes in Technology will perform better in Sciences. In a class of 145 students, the researcher studied only the males, wanting to make sure that gender does not interfere with the results. Thus only 76 male students were included in the study. All 76 students were given a Science Aptitude Test to assess their performance in Sciences at the beginning of the experiment. Out of the 76 male students, 40 were given classes in Technology for a whole academic year, and 36 weren't. At the end of the academic year, the Science Aptitude Test was repeated.
1. Performance in Sciences is the independent variable. *
5 points
True
False
2. The gender of students is the dependent variable. *
5 points
True
False
3. The group of 36 students is the control group. *
5 points
True
False
4. This is a survey study. *
5 points
True
False
5. This is a cross-sectional study. *
5 points
True
False
6. The operational definition of "Performance in Sciences" can be stated as "The score of students on the Science Aptitude Test". *
7 points
True because the operational definition explains how a certain construct will be measured.
True because the "Science Aptitude Test" was used to measure Technology Education.
False because the operational definition explains the control group.
False because this is the conceptual definition, not the operational definition.
7. The researcher is using a secondary source to collect data. *
7 points
True because female students were not included in the study.
True because the data collected are not about the researcher himself.
False. He is using primary source because he didn't do interviews.
False. He is using primary source because the researcher is collecting first-hand data through a test the he/she is conducting.

Please solve this for me I don't have enough time to finish it
