Math Problem Statement

How to create a scatter plot based on age and reaction time data, and analyze the relationship between these variables?

Solution

The image you've uploaded describes a task related to bivariate data, where you're instructed to investigate the relationship between age and reaction time using a ruler drop test.

Here’s a quick breakdown of the steps and data provided:

  1. Experiment Setup: You measure a person's reaction time by having them catch a falling ruler. The time it takes is recorded as "reaction time" based on the distance the ruler falls.
  2. Data Collected:
    • Ages of individuals: 9, 10, 15, 16, 20, 40, 38, 20, 23, 29, 15
    • Corresponding reaction times (in cm): 13, 12, 16, 11, 17, 18, 16, 12, 20, 18, 18

Instructions on Scatter Plot:

You are asked to create a scatter plot with:

  • X-axis (Age): Values range from 0 to 49 years.
  • Y-axis (Reaction Time in cm): Values range from 0 to 28 cm.

The data points should be plotted on the graph provided in the image.

Additionally, here are 5 questions you could consider after plotting the

  1. Does the reaction time seem to increase or decrease with age?
  2. Are there any noticeable outliers in the data?
  3. What type of correlation (positive, negative, or none) can you infer from the scatter plot?
  4. Could other factors aside from age influence the reaction time?
  5. How might you improve the experiment for more accurate results?

Tip: When analyzing bivariate data, always consider calculating the correlation coefficient to quantify the strength and direction of the relationship between the two variables.
