Does support for assisted suicide (“death with dignity”) vary by social class? Is this relationship dif-ferent in different nations? Small samples in three nations were asked whether it is ever justified for a per-son with an incurable disease to take his or her own life. Respondents answered in terms of a 10-point scale, on which 10 was “always justified” (the strongest support for “death with dignity”) and 1 was “never justified” (the lowest level of support). Results are reported here.
To test if social class and country of a person affect support for assisted suicide (“death with dignity”), we will conduct a two-way ANOVA. Here, the factors of interest are the social class of a person with four levels i.e., lower, working, middle and upper and country with 3 levels: Canada, Mexico and US. The response variable is the answers in terms of a 10-point scale, on which 10 was “always justified” (the strongest support for “death with dignity”) and 1 was “never justified” (the lowest level of support). Assume 0.05 significance level.
Null hypotheses:
H01: There is no difference in average scores on 10-point scale among different social classes (social class of a person does not affect support for assisted suicide).
H02: There is no difference in average scores on 10-point scale among different nations/countries (the relationship is same for all nations).
H03: There is no interaction (the relationship b/w social class and assisted suicide is same for all nations).
Decision: Reject H0 is p-value < 0.05.
We will use R software for calculations.
