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.
True
This statement is true because a non-directional hypothesis simply predicts that a relationship or
difference exists but does not specify the direction.
b) In a study testing a directional hypothesis, the critical region for rejecting the null hypothesis is split
into two tails of the distribution.
False
In a directional hypothesis, the critical region is located in only one tail because the hypothesis
predicts the direction of the effect.
c) A non-directional hypothesis always predicts that there will be no difference or relationship between
variables.
False
A non-directional hypothesis predicts that a difference or relationship exists but does not specify the
direction, unlike a null hypothesis, which predicts no difference or relationship.
1.2 Formulate a directional hypothesis based on the context:
Directional Hypothesis:
"The new teaching method will result in significantly higher test scores compared to the traditional
teaching method."
