Hi Dad, This is a test document that I am running to experiment if this webpage can be shared publicly. Rpubs is a tool to share your work and code with other people and make your research reproducible.

Can you let me know if you can see this on your side?



Point 1: The Data

head(cars)

Point 2: The Visual

cars %>% ggplot(
  aes(x=speed, y=dist)) + 
  geom_point(color = "darkblue") + 
  theme_light() + 
  labs(x= "Distance Traveled", 
       y = "Car Speed", 
       title = "The Affect of Car Speed on Distance Traveled")


Point 3: The Stats

model = lm(speed ~ dist, data= cars)
summary(model)

## Residual standard error: 3.156 on 48 degrees of freedom
## Multiple R-squared:  0.6511, Adjusted R-squared:  0.6438 
## F-statistic: 89.57 on 1 and 48 DF,  p-value: 1.49e-12

  • Based on the 1.49e-12 P value: We see that distance is a significant predictor of speed. In other words, when the distance that a car travels increases, its speed often increases with it
  • A linear relationship between the two variables has been identified.
