Taste Test Flyer

By: Payton, Maria, Dalton and Jonah

Hello, my group members and I have preformed a blind taste test on a group of 130 7th grade students. We preformed our test on Original and Baked Lays. Our test was a triangular test so we were testing to see if our participants could tell the difference between the two. We hypothesized that our participants wouldn't be able to tell the difference between the two chips.

RESEARCH:

We had to do some research before we did our experiment. We found out that they were made in Dallas, Texas.The person who made Lays Original as C.E Doolin. They were made in 1932 and they were invented in C.E Doolin's kitchen when he got the idea of making chips from a bag of chips he saw at a cafe'. Our group members had to split up the research and put it all together in the end. We spent about 3 days researching before we could preform our taste test.

Materials and Procedure:

For the actual taste test we had to collect all of our materials. We had to,

  • Make a spread sheet to collect the data
  • Plan out how we were going to preform our test
The materials we needed were,

  • Gloves
  • Two bags of each type of chips
  • A table to work on
  • Paper plates
  • An iPad to help collect data
For the procedure we were first going to

  • hide the bags of chips so the participants don't see what types of chips we have.
  • The we put the plates on the table and put the chips in order according to the spreadsheet.
  • Then we tell the experimenter what to do and had them eat the chips and put in there opinion.
Their option went to a data sheet so we could keep track of how many people were right and wrong.

More Info:

The members of our group figured that people would be able to see the difference between the chip because the baked chip was looked much dryer. So if we made it a blind test then they wouldn't be able to tell the difference.

Collecting Data:

To collect this data we used spread sheets. We set out an iPad with the spread sheet on it and when the participant was finished they could send in their data. The data then goes to another spreadsheet showing the results of all the experimenters. We use the information from the second spread sheet and used to make our graphs. Our graphs show which people were right and wrong on a bar graph.

Results:

Our results came out that 15 out of 45 people got it wrong, so that leaves the other 30 who got it right. So this proves that our prediction was rejected. If we were to do this test again I would change a one thing. I would change is how we made it a blind test. I think we should have covered the plate with the chips on it too because when the participant got to the station, the first thing they did was look at the chips so if we were to cover it I think more people would have gotten it wrong.
