because the authors are looking to examine the mean difference between the same variables but across two different groups (ambivalent vs supportive) (Reblin, et al., 2016). Since the purpose is to find out if a relationship has an effect of perceived burden, anxiety & depression, using an independent t test allows for the collection of data that will determine if there is significant statistical difference or not. The similarity is that both t test try to determine the difference between two means is significant. The test done on both articles tries to measure perceived burden & anxiety levels. A significant difference occurs when using a matched t test, it compares the scores on two different variables but for the same group. (In this case same individuals but over two different time periods). There is a relationship between the observations collected in both samples (second sample collected is dependent on the first). In the second article, An Independent t test is used to examine if there is a difference in the means of two different groups (In this case ambivalent vs supportive). Sample is collected randomly and independently (Reblin, et al., 2016). In the first article, the Matched pair t test reduces error. Variance within subjects is typically smaller than between subjects (Grunfeld, et al., 2004). The Matched t test that was used in the first article also do not require many subjects to achieve the same results as it is required in the independent sample t test. While in the second article, Homogeneity of variance allows for the assumption that when conducting independent t test, variance within each population is equal. By having equal variance, it strengthens the credibility of p-values that are used to reject / accept a hypothesis. Some limitations for these tests would be that there is Potential for carry over, which is a type of practice effect that occurs because the results from one test influences the other. Since participants of this study are being tested twice, they can become aware of the purpose which can influence their behavior leading to possible errors in the result. The need for a larger sample size to conduct experiments is a disadvantage of independent t test. Since two groups are required, testing for an independent t test requires a lot more participation in order to reduce errors and generate a reliable result.

Conclusion

These two articles are in relation to the burdens that is put on family members in playing the role of a caregiver for the family members. In the first article, the family caregivers are burdened with the responsibility of caring for the cancer patient, and the decision to do this can have its adverse effect on the caregiver too. The first article also researched on the psychosocial, occupational and economic effect on the caretaker. According to the article, the result of the research that was done was that caring for their loved ones impacted their work because they had to miss work to care for the cancer patient, also paying for the prescription drugs also was a financial burden too. The explanation for this is that Caregivers’ depression and perceived burden increase as patients’ functional status declines. Strategies are nee
