A Simple Way to Conduct Your Own Water Taste Test
Many tests have been conducted to determine consumer preferences for bottled water or tap water. Some encompass detailed statistical tests such as chi-square, goodness-of-fit, and independence tests. The data revealed from these tests are complex, yet provide the conductor with valuable information and the ability to compare assumptions with reality.
For this article, I want to provide all readers with the opportunity to conduct their own water taste test, not entailing the above complex formulas. The following are steps in which a water taste test can be performed on a local basis:
Step 1: Determine Testing Group
Gather a sample size of participants to partake in the test based on population and confidence level. This sample size should be substantial enough to represent a specific population such as a city or state. Click here for a sample size calculator.
Step 2: Prepare Testing Materials
Choose a convenient and neutral location to conduct your test.
Set up the number of cups for each participant in accordance with the number of items you will be comparing. Mark each cup accordingly so you will recognize which type of water was poured into which cup.
Pour the different types of water into their designated cups. For example, if you are simply comparing one type of bottled water to one source of tap water, pour the bottled water into all the cups marked A, and pour the tap water into all the cups marked B.
Provide a sheet of paper for the participants to rank the choices from “most preferred” to “least preferred.” In addition, make room for the participants to leave any commentary. You may adjust the questions to your liking.
**Make sure to remove all brand-related packaging from the view of the participants in order to get unbiased results.**
Step 3: Execute Test
When all the participants are comfortably in the room, tell the participants to first sample cup A and write down their thoughts. Then repeat this step with cup B, and so on and so forth for as many items you are testing.
Step 4: Analyze Data
If you are computer savvy and can provide statistics using various programs such as Excel, Minitab, or SPSS, do so to ensure a more accurate analysis. If this is not within your ability, you can simply tally up your answers and present them in whichever way communicates the answers best.
There you have it! A simple, yet effective way to perform your own water taste test. If you choose to conduct a test in your local area, please let us know!
