QUESTION 1 [5] 1.1 Indicate whether the following
statements are True or False. a) A non-directional
hypothesis is used when there is no prior theoretical basis
for predicting the specific direction of the effect or
relationship between variables. (1) b) In a study testing a
directional hypothesis, the critical region for rejecting the
null hypothesis is split into two tails of the distribution. (1)
c) A non-directional hypothesis always predicts that there
will be no difference or relationship between variables. (1)
Here are the answers to the statements:
a) True
A non-directional hypothesis is used when there is no prior theoretical basis for predicting the
specific direction of the effect or relationship between variables. It only predicts that there will
be a difference or relationship, but not the direction.
b) False
In a study testing a directional hypothesis, the critical region for rejecting the null hypothesis is
located in one tail of the distribution, not split into two tails. A non-directional hypothesis would
have the critical region split into two tails.
c) False
A non-directional hypothesis does not predict that there will be no difference or relationship
between variables. Instead, it predicts that there is a difference or relationship, but without
specifying the direction.
1.2 A researcher is investigating the effectiveness of a
new teaching method in improving students’ test scores
relative to a traditional teaching method. The researcher
anticipates that the new method will result in significantly
higher test scores based on prior research findings. Based
on this context, formulate a directional hypothesis. (2)
