The six most common forms of hypotheses are:

Hi, Can you help me create a statement of the problem regarding this topic: “Comparing the effects of urine and rice water to mongo plants against commercial fertilizer”. Thank you!

Here are a few examples of questions to be answered:

for obese patients have a mean of 100 with a standard deviation of 15. A researcher thinks that a diet high in raw cornstarch will have a positive or negative effect on blood glucose levels. A sample of 30 patients who have tried the raw cornstarch diet have a mean glucose level of 140. Test the hypothesis that the raw cornstarch had an effect.

How to Write a Problem Statement for Six Sigma

In looking at this example, we consider two different versions of the same problem.

: In everyday language, generally refers to something that a fortune teller makes about the future. In science, the term generally means "what we would expect to happen or what we would expect to observe if this idea were accurate." Sometimes, these scientific predictions have nothing at all to do with the future. For example, scientists have hypothesized that a huge asteroid struck the Earth 4.5 billion years ago, flinging off debris that formed the moon. If this idea were true, we would that the moon today would have a similar composition to that of the Earth's crust 4.5 billion years ago — a prediction which does seem to be accurate. This hypothesis deals with the deep history of our solar system and yet it involves predictions — in the scientific sense of the word. Ironically, scientific predictions often have to do with past events. In this website, we've tried to reduce confusion by using the words and instead of and .

Looking for some examples of hypothesis

By saying “Having too few forklifts” in Poor Problem Statement 1B, you’re purporting that you know what the solution is. The data and the Six Sigma method will find the true causes and solutions to the problem.

An Example of a Hypothesis Test - ThoughtCo

Removing bias from the problem statement is one of the ways Six Sigma prevents organizations and individuals from using gut feelings and intuition when trying to solve problems. Problem statements such as the following are effective at enlisting peoples’ attention, energy, and support:


How many times have you heard a problem statement like this one before? Yes, having high inventory levels is a problem, but a problem statement containing so little information significantly reduces your ability to take specific action, enlist support, and obtain improvement.

Before the MVP: How to craft a hypothesis statement

Better Problem Statement 1: Inventory levels at the West Metro inventory storage process in Scottsdale are consuming space, taking up asset management time, and creating cash flow issues. Inventory levels are averaging 31.2 days, with a high of 45 days. These levels have exceeded the target of 25 days 95 percent of the time since January 2012. $250,000 could be saved per year if inventories were at the targeted level.

Understanding the four components of a hypothesis statement, ..

Look at the amount of information that is available in this example. You know where the problem is occurring, you know how long it has occurred, you know the magnitude of the problem, and you know how much it’s costing. Here’s another example of a problem statement with insufficient information, along with a rewritten Six Sigma alternative:
