Imagine I've conducted a study to examine the correlation between how many hours of sleep people get and their levels of relationship satisfaction. I analyze my data and find that these two variables are correlated at r = 0.34.
a. If I created a scatterplot of this correlation, what would the regression line/line of best fit look like? Describe it.
The regression line/line of best fit in the scatterplot would have a positive slope, indicating a positive correlation between the number of hours of sleep and levels of relationship satisfaction. The line would be upward sloping from left to right, suggesting that as the number of hours of sleep increases, the levels of relationship satisfaction also tend to increase. However, the slope would not be very steep, indicating a relatively weak correlation between the two variables.
