Example Of Dependent Variable Is The Rate Of Performance Caused By The Different Amounts Essay

Question 1

1A. the independent variable would be the amounts of new energy drink “Blast”

1B. in this case, the rate of performance caused by the different of amounts of “Blast” would be any effect apart from the normal performance rate of an individual i.e. the change in the performance resulting from administration of “Blast”
1C. the control group would be a group of participants to which no “Blast” is administered.
1D. placebo effect is the change caused by expectation, i.e. administration of three levels of “Blast” may cause change in performance even when it has no effect. Therefore, it is good for the researcher to pay attention the effects of placebo response i.e. expected results that may alter the outcome of the results.
1E. Activity varies depending on age, therefore, holding the age of the participants constant would be of benefit to the results.
1F. no, random assignment or selections may not yield the best result due to variation in sample characteristics. Systematic sampling would be more appropriate.
1G. one possible confounding effect is the personal experience or prior motivation to perform.
1H. double-blind procedure is the experiments design whereby both the administrators and the participants in the research do not know each other. In the experiment, double blind should be used in the whole process of selections and administration of “Blast”
1I. The research method may not be effective since placebo effect may override the results. This can happen if double-blind procedure is not used.

Question 2

2A. I would set up an experiment whereby one group would be administered with increasing levels of “Blast” while the control group shall not. I would then administer intelligence exam and test for correlation using Pearson moment correlation coefficient.
2B. No, blast can boast level of intelligence by possibly affecting some part of the brain. In this case, Blast would not be the cause of intelligence, but would activate another underlying factor that would be the cause.
2C. increased sporting activity.

2D. increased dependency to “Blast” for performance

2E. the two variable are strongly negatively correlated i.e. consumption of “Blast” does not cause and increase in intelligence.
2F.

Question 3

Question 4
4A. No, Waldo may not be smart because of his grade, the exam might have been easy or he could have had other advantages that led to the high scores.
4B. Waldo’s intelligence could partly be due to genes. At this time, it would be impossible to tell the exact cause of Waldo’s intelligence without proper research. There are other factors that influence intelligence such as intelligence where buy twins brought up in different region have different levels of IQ.
4C. first, make sure that the intelligence is objective, is precise, clear, and is neural, i.e. can be taken by any other person and give right result. It would be wrong to make the test with Waldo in mind since that may lead biases.
