Scatter Plot

My scatter plot has no correlation and my two variables are walmart and target incidents. There are no outliers. There is no linear relationship either.

My signifigance level is .05 because the variation is moderate. Weak correlation

My line of best fit is y=171.28464x + .0044184021

Simple linear regression results:

Dependent Variable: Target Incidents
Independent Variable: Walmart Incidents
Target Incidents = 171.28464 + 0.0044184021 Walmart Incidents
Sample size: 32
R (correlation coefficient) = 0.0069340322
R-sq = 0.000048080803
Estimate of error standard deviation: 100.76015

Parameter estimates:

Error 30 304578.23 10152.608
Total 31 304592.88

Y intercept is 171.28464

Correlation Coefficient is .0069340322

Slope is .0044184021

R squared is .0000448080803

My line of best fit doesn't seem to touch any of the point because there is no correlation. My terms are significant.

Graph with line of best fit

The line of best fit doesn't seemt to work with this data becaue there is no correlation. My points are not correlated and there is no relation.

EC 1 Yes on the residuals graph they seem to follow a normal distribution.

EC 3 Yes I got different results.

EC 2 The graph is still similar with no correlation.

EC 5 Multiple linear regression graph
