Hypothesis Testing and Experiment Design

These flashcards cover key concepts and processes involved in hypothesis testing and experimental design.

What is the purpose of testing a hypothesis in an experiment?

To determine whether the hypothesis is supported or rejected by the experimental data.

What are the necessary components to include in the 'Materials' section of an experiment?

Amounts of materials, specific brands if important, and a detailed list.

What should be included in the procedures of an experiment?

A numbered list of each step starting with an action word to ensure replicability.

What is the role of the Experimental Group in an experiment?

It includes the groups being tested where the independent variable is manipulated.

What distinguishes the Control Group in an experiment?

It serves as a comparison group that does not receive the experimental treatment.

Why is it important to have as many trials as possible in an experiment?

To ensure that results aren’t due to chance and increase the precision of the data.

What are Constants in an experiment?

Aspects that are held constant to ensure that any changes in the dependent variable are due only to the independent variable.

What is the importance of analyzing data in an experiment?

To ensure that trials are identical except for the independent variable, allowing valid conclusions.

What should be included when drawing conclusions from experimental data?

An explicit statement about whether the hypothesis was supported or rejected and real-world applications of the findings.

How should data be presented for analysis?

In an organized form such as a data table or a graph for easy readability.
