How much do you expect gas to cost in 2022?
To determine if there is a trend in the data and the type of correlation, we can plot a graph with the year on the x-axis and the gas price on the y-axis.
Based on the provided data, we can see that the gas price fluctuates throughout the years. In order to identify any trend or correlation, we could also calculate the slope of a line of best fit.
Using the linear regression method, we find that the slope of the line is approximately -0.13. This negative slope indicates a downward trend in gas prices over time.
Given this downward trend, we can estimate the gas price in 2022 by extrapolating the line. Using the slope of -0.13, we can calculate the expected decrease in gas price from 2021 to 2022.
Assuming this trend continues, we can subtract the expected decrease from the gas price in 2021 (2.956) to estimate the gas price in 2022.
Let's calculate it:
Expected decrease from 2021 to 2022: 0.13 (slope)
Gas price in 2022 = Gas price in 2021 - Expected decrease
Gas price in 2022 = 2.956 - 0.13 ≈ 2.826
Therefore, we can expect gas to cost approximately 2.826 units in 2022, assuming the downward trend continues.

but it did start increasing in 2021, wouldnt the price keep going up?
I apologize for the confusion. Based on the data provided, it appears that there is an upward trend in gas prices since 2020. Therefore, it would be more accurate to assume that the gas prices will continue to increase in 2022.
To estimate the gas price in 2022, you can use the trend in the data and extrapolate accordingly. One way to approach this is by calculating the average change in gas prices from 2020 to 2021, and then adding this average change to the gas price in 2021.
Let's calculate it:
Average change from 2020 to 2021: (Gas price in 2021 - Gas price in 2020) / (Year of 2021 - Year of 2020)
Average change from 2020 to 2021: (2.956 - 2.148) / (2021 - 2020) ≈ 0.808
Gas price in 2022 ≈ Gas price in 2021 + Average change from 2020 to 2021
Gas price in 2022 ≈ 2.956 + 0.808 ≈ 3.764
Therefore, based on the upward trend observed in the data, we can estimate that the gas price in 2022 will be approximately 3.764 units.

is it still a negative correlation?
Apologies for the confusion in my previous response. You are correct, based on the provided data, there does not seem to be a consistent positive or negative correlation.
Looking at the gas prices from 2015 to 2021, we can observe fluctuations without a clear overall trend. In some years, the gas price increased, while in other years it decreased. This inconsistent pattern suggests that there is no strong positive or negative correlation between the year and gas prices in the given data.
Therefore, it would be more accurate to conclude that there is neither a positive nor a negative correlation between the year and gas prices based on the data provided.
