Answer :
### A. Fastest Simpson with Crossword Puzzles
To determine the fastest Simpson, we look at the average times taken by Bart, Lisa, and Homer to complete the crossword puzzles over the four-week period:
- Bart: [tex]\(17.00\)[/tex] minutes
- Lisa: [tex]\(4.25\)[/tex] minutes
- Homer: [tex]\(40.50\)[/tex] minutes
By comparing these average times, we see that Lisa has the lowest average at [tex]\(4.25\)[/tex] minutes. Therefore, Lisa is the fastest Simpson with crossword puzzles.
### B. Experimental Variable
In this experiment, the experimental variable is the time taken to complete the crossword puzzle. This is the variable that is being measured and recorded for each participant (Bart, Lisa, and Homer) each week.
### C. Possible Explanations for Differences Observed
There are several potential reasons for the differences in the times it took for Bart, Lisa, and Homer to complete the crossword puzzles. Two plausible explanations include:
1. Variations in Cognitive Abilities and Problem-Solving Skills: Different people have varying levels of intellectual capabilities and problem-solving techniques, which can affect how quickly they can complete tasks such as crossword puzzles.
2. Differences in Familiarity with Crossword Puzzles or Frequency of Practice: The amount of experience each individual has with crossword puzzles can greatly influence their performance. If one person practices more frequently or has more familiarity with common crossword puzzle tricks and vocabulary, they are likely to complete the puzzles faster.
### D. Additional Experiments to Determine Causes of the Differences
To gain a better understanding of what might be causing these differences, we can recommend additional experiments that involve different types of cognitive tasks:
1. Use a Different Type of Puzzle or Mental Challenge:
- Conduct the experiment with other types of puzzles or mental challenges, such as Sudoku, logic puzzles, or even brain teasers. This could help determine if the observed speed differences are consistent across various types of cognitive challenges.
2. Measure Performance on Puzzles of Varying Difficulty:
- Introduce puzzles that vary in difficulty levels and measure the time taken to solve these puzzles. This can provide insight into how each individual's performance changes with puzzle complexity and whether the differences in performance are more pronounced on easier or harder tasks.
These additional experiments can help pinpoint whether the ability to quickly solve crossword puzzles is related to general cognitive skills, familiarity with specific types of puzzles, or a combination of other factors.
