What does a null hypothesis (H0) state in research?

• There is no effect

• No difference exists

• Variables are unrelated

• There is no significant relationship between variables

What does an alternative hypothesis (H1) claim?

• There is an effect

• A difference exists

• Variables are related

• There is a significant relationship between variables

What question should a researcher ask first when formulating hypotheses?

• What is being tested?

• How are variables related?

• Why are variables important?

• Which variables are included in the problem statement?

What should a researcher develop before writing a hypothesis?

• Data Analysis

• Research Title

• Testable Question

• Testable problem statement

• H0: The use of study planners has no significant effect on time management; H1: The use of study planners has a significant effect on time management

What is the main purpose of gathering related literature in research?

• To find articles that support the research topic

• To summarize all sources found on the internet

• To determine what has been studied from the topic
