Now, you might think it's kind of "cheating," or "stacking the deck," to "go out on a limb" like this and state your prediction BUT that leads us into the one key property that ALL hypotheses should possess : namely, they must be in testable form! For that will be the purpose of your research design and analysis: to scientifically and objectively gather your evidence data ; AND then revisit your original "guess-timate," or hypothesis and then decide: Shall I "keep believing it?
If so, you are "retaining" your hypothesis! Is this evidence 'strong enough' to lead you, then to ' quit believing' your hypothesis and switch to another belief? This is called "rejecting" your hypothesis! That is: when is the numeric evidence from your study sample "strong enough" to "safely" reject your original hypothesis in favor of another belief about reality!!! What makes an hypothesis "non-testable? These tend to come in two 2 forms: The researcher has accidentally left out a basis for comparison.
Is it Method A to some other method? Or is it the students to themselves: e. Note how, in our example of a peer-assisted statement vs. That is: Method B peer-assisted is being compared to Method A traditional. Quite often, though, with a little work and effort ah Example: "All junior high school age boys should be required to take a course in home economics.
Please note the " should "! It may represent what you honestly feel or believe But one way to begin to 'massage' this into an eventually researchable and testable hypothesis might be to ask the person making the statement, " Why do you feel this way?
Now, we will not be able to 'scientifically and objectively conclude' e. We might then propose the following hypothesis: "Junior high school age boys who have taken a course in home economics will exhibit significantly less sex-role-stereotyping behavior than junior high school age boys who have not taken a course in home economics.
This is called " operationally defining your variables :" in a way that's generally acceptable and can therefore serve to determine whether that variable 'is' or 'isn't there' in a given situation. There is a way to 'tell' or 'determine' if the behaviors decrease after the exposure of the boys to the home economics course.
Therefore, this particular hypothesis can be tested -- and then, of course, retained or rejected once the study evidence is in! To help you determine that your experimental results are valid.
The control group consists of elements that present exactly the same characteristics of the experimental group, except for the variable applied to the latter. This group of scientific control enables the experimental study of one variable at a time, and it is an essential part of the scientific method.

Research Paper. Ben Davis June 1, What is the difference between problem statement and purpose in research study? What is the purpose of problem statement? What are the parts of statement of the problem? Should I put my name on my statement of purpose? Without a problem, you have no real reason to conduct the experiment or understanding on what to conduct an experiment on. The problem statement guides the strategic direction of your experiment while ensuring that you are always focusing on the customer.
The data and research that you undertake will help you identify customer problems, either for your current customers or for your target audience. This enables you to triangulate insights so that you can build a more complete picture of the problem, whilst also gaining an understanding of the magnitude of the issue. Rather than letting this put you off, it is better to dig deeper, ask more questions and achieve a greater understanding of the customer problem before trying to find a solution.
With this in mind, it is wise to collaborate with other teams within your business — preferably members of your CX and UX departments — who may be able to share relevant customer insights that they have discovered through their own research. Once you have sufficient data, it is likely you will start to identify problem themes, which will help you understand the wider issues your customers are facing.
This is where we start to create a clear problem statement. A clear problem statement should help you identify what the problem is and the data that backs up your claim. At CreativeCX, we organise each problem statement as follows:.
Through our research, we discovered the following two pieces of data:. Usability testing showed users were moving back and forth between the product details page and the basket page to edit their selected size. Based on this analysis, we have inferred a problem: users are struggling to understand which size they should choose. Through this, we are able to make the following problem statement:. Is my problem statement focused on my customers? Is my problem statement clear and precise? What data do I have to back up this problem?
As you can see in the examples above, our first example answers all three questions while the second statement falls short on questions two and three. Whilst your problem statement identifies the problem you hope to solve, the hypothesis helps you decide on how you will try to solve it. Essentially, the hypothesis statement is a prediction for what you think will happen if you take a certain type of action to resolve a problem. Rushing over this critical step could mean that you miss out on key actions or insights further down the line.
Similar to the problem statement, the hypothesis should be precisely constructed. An unclear problem statement or hypothesis could, in turn, result in your proposed solutions not having the desired or expected results. There are many ways to write a strong hypothesis. At CreativeCX, we structure ours using the following formula:. By [state experiment change], we believe [user behaviour change], solving [state problem].
We expect to see [expected results]. Now, some may say this will create a hypothesis that is too lengthy. However, this structure clearly incorporates three key elements of an experiment: the problem we are trying to solve, the specific execution, and the expected result.
