Introduction
Our group consisting of Katy Canter, Hunter Whiteman, Jesse Dearth, Brandon Brinely, and Luke Campbell, have observed some of the local stores that promise they have the best prices. For example Kroger's slogan is "Right store, Right price.", and Walmart's slogan is "Save money, live better.", along with the other stores making the same promises in their slogans. We began to wonder, which of our local stores offers the best deal's on food and other household items? Our group hypothesizes that if we go to these stores and buy the same 15 items and add up the final price, we will find the cheapest place to shop. We also hypothesize that Kroger will have the cheapest prices because Kroger always has sale ads out and bundles items together for cheaper prices.
Materials and Methods
Katy will be going to Dorothy Lane Market, Jesse Dearth will be going to Marsh, Brandon Brinely will be going to Meijer, Hunter Whiteman will be going to Walmart, and Luke Campbell will be going to Kroger. These are the 15 items that each member will purchase.
- Cool Ranch Doritos
- Lucky Charms
- One 2 liter of Dr. Pepper
- Hershey's syrup
- Kleenex tissues
- Yoplait keylime yogurt
- 1 gallon of 2% milk
- Beef Ramen Noodles
- Loaf of Wonder Bread
- Clorox wipes
- Oreo's
- Secret Deodorant
- Skittles
- Tropicana Orange Juice
- Cottonell toilet paper
After they have recorded the shelf prices of these 15 items, we will put all our data into a table and turn that into a line graph. Then we can tell which store had the lowest final price.
Results
This is a table showing the differences in the prices of items at each store.
This is a chart where the prices of all the items of each store are recorded.
Discussion
We have concluded that the cheapest place to shop for everyday items is Walmart. The total prices for each of the stores is as follows:
Kroger: $40.87
Walmart: $35.23
Meijer: $43.89
Dorethy lane Market: $40.04
Marsh: $46.86
As you can see our hypothesis that we had originally made was incorrect because we said that Kroger would be cheapest when actually Walmart was the cheapest place to shop. Some possible errors that might have effected this experiment were the time all of the data was collected. If you recorded Walmart's data two weeks before Kroger's then the prices might have changed within that span of time. Some variables that could have changed the Outcome of the prices are sales, coupons, specials Anything along those lines that could have effected the end price of all the items.
