Unit 3 Project by Jayden Perkins

Purpose

jaydenperkins1 — 2024-03-06 21:10:00 UTC

How much water do families in Roseville use per day? The data that our class researched came from google classroom and took all those numbers and put them in google sheets and we did that so we can find how much water our class uses as a whole.

Question

jaydenperkins1 — 2024-03-06 21:12:09 UTC

Is there a relationship between household size and water usage? What does the r value tell us in our last squares regression line? Is this a spurious or casual relationship? Are there any meditating or confounding variables that help explain the story?

Analyzing

Data Purpose and Collection

jaydenperkins1 — 2024-03-07 20:02:39 UTC

The Purpose of this project is to determine how much water the average household uses, and also to figure out weather that is a reasonable amount of water use. To collect data to answer the question. We took multiple surveys to figure out the average amount of water me and my household uses per day, then I analyzed the data that the state of California had collected and compared the two together.

Explaining Slope,Y intercept and r²

The R values are near where they should be at 0.07 which is not above .35.(r² =0.26) which is not about S6 its extremely below and that is a meaningless relationship that which is going to cause the data to be very unreliable because there is many errors which will effect the end outcome and overall outcome. For the slope it is 79.1 and for the y intercept it is 97.7 that means that for every person, when you are using water for anything the amount goes up 79.1 gallons but when no one is on the water or using it is 97.7.

My Final Statement

jaydenperkins1 — 2024-03-12 04:50:55 UTC

It does not really matter how big your household is that effects the water usage. The water usage is how you decided to use that water. High water usage can be caused by just taking long showers or leaving the water running when its not necessary. So my intake is that it dosent matter how big of a family you have, if you abuse water then you are going to have a high water usage and if you can use water properly you will be just fine on the amount of water you are using.

Predictions

I definitely think you can use this imformation to predict the water usage for larger household and even our school and same goes for the city and state because city population and water usage in cities are pretty much the same thing because city population and water usage in cities are pretty much the same thing because of having the highest r2 value of 65 percent. I also think we could make these predictions based on our model because our whole class of families are going to be similar to everyone else

y=.133(151.901)+76280=96,482(1000)=964,828,333 and I think its reasonable because it is correlated.
