How do I test this hypothesis:
The first thing that needs to be tested is whether people actually feel negative after the test (a so called manipulation). Given that emotions were measured with four questions (feeling: bad, sad, dissapointed and angry) on a scale ranging from 1 to 7, you can test the general direction of their affect by testing against the midpoint of the scale. Test the following hypothesis:
(H1) People feel negative after the test
Which test should I do? One sample t test? And also the value lables are only specified 1 = not at all and 7 = very strong. Should i also specify 2-6?
