If the plotted points in a scatter diagram are evenly distributed, then the correlation is
Detailed Solution for Test: Correlation And Regression- 1 - Question 11

When points in a scatter diagram are evenly distributed in a random pattern, it means that there is no discernible trend or relationship between the two variables being plotted. This lack of a pattern indicates that as one variable changes, the other does not change in any predictable way.

In terms of correlation:

  • Positive correlation: The points would trend upward from left to right, indicating that as one variable increases, the other also increases.
  • Negative correlation: The points would trend downward from left to right, indicating that as one variable increases, the other decreases.
  • Zero correlation: The points are scattered randomly without any clear upward or downward trend, showing no relationship between the variables.

Therefore, when the points are evenly distributed in a scatter diagram without any discernible pattern, the correlation is zero, meaning there's no linear relationship between the variables.

Detailed Solution for Test: Correlation And Regression- 1 - Question 14

The correct option is Option C.

When brakes are applied to a moving vehicle, the distance it travels before stopping is called stopping distance. It is an important factor for road safety and depends on the initial velocity (v0) and the braking capacity, or deceleration, -a  that is caused by the braking.
