3 important questions on Summary Hand-out I
Statement of hypotheses: formats If-then statements:
A hypothesis can also test whether there are differences between two groups (or among several groups) with respect to any variable or variables. To examine whether or not the conjectured relationships or differences exist, these hypotheses can be set either as propositions or in the form of if-then statements. The two formats can seen in the following two examples:
· Employees who are more healthy will take sick leave less frequently.
· If employees are more healthy, then they will take sick lesave less frequently.
· Employees who are more healthy will take sick leave less frequently.
· If employees are more healthy, then they will take sick lesave less frequently.
The hypothetic – deductive method:
A method that requires that hypotheses are falsifiable: they must be writtin such a way that other researcher scan show them to be false. As such, hypotheses are sometimes accompanied by null hypotheses.
A null hypothesis (H0):
Is a hypothesis set up to be rejected in order to support an alternate hypothesis, labeled HA. When used, the null hypothesis is presumed true untill statistical evidence, in the form of a hypothesis test, indicates otherwise. Typically, the null statement is expressed in terms of there being no (significant) relationship between variables or no (significant) difference between two groups.
