# Simulated data for analyzing the relationship between watching TV and grades

Source:`R/data-gradestv.R`

`gradestv.Rd`

This is a simulated data set to be used to estimate the relationship between number of hours per week students watch TV and the grade they got in a statistics class.

## Format

A data frame with 25 observations on the following 2 variables.

- tv
Number of hours per week students watch TV.

- grades
Grades students got in a statistics class (out of 100).

## Details

There are a few potential outliers in this data set. When analyzing the data one should consider how (if at all) these outliers may affect the estimates of correlation coefficient and regression parameters.

## Examples

```
library(ggplot2)
ggplot(gradestv, aes(x = tv, y = grades)) +
geom_point() +
geom_smooth(method = "lm")
#> `geom_smooth()` using formula 'y ~ x'
```
