What type of SPSS test would you do to prove or disprove the hypothesis "People in a relationship are happier than those who are not?"
case 1:
independent variable -> relationship. this is measured by the nominal scale of measurement. the has two categories namely yes and no. these two groups are not related to each other.
dependent variable -> happiness. this is measured by the ratio scale of measurement.
T-test for independent samples will be used to test if there is a significant difference in the mean happiness between those in a relationship and those who are not.
Ho: there is no significant difference in the mean happiness
between those in a relationship and those who are not.
V/s h1: there is a significant difference in the mean happiness
between those in a relationship and those who are not.
case 2:
independent variable -> relationship. this is measured by the nominal scale of measurement. the has two categories namely yes and no. these two groups are not related to each other.
dependent variable -> happiness. this is measured by the ordinal scale of measurement.
Chi-square of independence will be used to test if there is a significant difference in the happiness level and relationship status.
Ho: there is no significant difference in the happiness level
and relationship status.
V/s h1: there is a significant difference in the happiness level
and relationship status.
