Question

questions:

1. how would you describe the trend in the data? what does it tell you about how practice affects reaction time?
2. if you drew a line to represent this trend, how could it help a new player predict their reaction time?

Explanation:

Step1: Analyze the trend in the scatter - plot

As the minutes of daily practice (x - axis) increase, the reaction time (y - axis) decreases. This shows a negative correlation. It means that more practice is associated with a shorter reaction time.

Step2: Explain the use of a trend line for prediction

A trend line (regression line) would show the general relationship between practice time and reaction time. A new player could use the line to predict their reaction time for a given amount of practice. For example, if a new player plans to practice for 30 minutes, they can look at the value on the trend line at \(x = 30\) to estimate their reaction time.

Answer:

1. The data shows a negative trend. As the minutes of daily practice increase, the reaction time decreases. This tells us that more practice leads to a shorter reaction time.
2. A trend line would show the general pattern of the relationship. A new player could use the trend line to predict their reaction time for a specific amount of practice. They would find the value of practice time (e.g., \(x\) minutes) on the x - axis, then go up to the trend line and over to the y - axis to get an estimate of the reaction time.
