  1. Math 1040 Semester Project ~ Group 6 ~ Kimberly Jorgensen, Daniel Lollathin and Whitney Woodruff

  2. Research Question • Is there any relation between the number of hours of sleep an individual gets and the amount of caffeinated beverages consumed daily?

  3. Data Collection • We decided to take a systematic sampling approach and sample between ten and twenty individuals each, resulting in a sufficient sample size of over 30 people.

  4. Variable 1 Data – Hours of sleep

  5. Variable 1 Statistics– Hours of sleep • Mean: 6.78 • Standard deviation: 1.36975 • Five-number summary • MIN: 2 • Q1: 6 • Median: 7 • Q3: 8 • MAX: 10 • Range: 8 • Mode: 7 • Outliers: 2

  6. Variable 2 Data – Caffeinated drinks

  7. Variable 1 Statistics– Caffeinated drinks • Mean: 1.5 • Standard deviation: 1.6507 • Five-number summary • MIN: 0 • Q1:0 • Median: 1 • Q3: 2 • MAX: 7.5 • Range: 7.5 • Mode: 0 • Outliers: 5, 5, 5, 6, 6, 7.5

  8. Calculations Correlation coefficient: -.2956 • Line of regression: • Y=-.2466x+7.1499

  9. What does this mean? • The critical value for the line of regression in this case is near .205. With a result closer to .3 it would appear that there is a very weak relationship between our variables, but it is still statistically significant.

  10. Difficulties and Surprises Encountered • We felt like one difficulty was the determination on the amount of caffeine consumed. Different types of drinks hold varying amounts of caffeine. • It is difficult to compare the amounts of caffeine per drink

  11. Difficulties and Surprises Encountered (cont.) • Another difficulty in this type of study is the awareness and honesty of the individual being sampled. Being unaware how much sleep vs. caffeine consumed makes this study difficult. • We were also surprised that there was not a stronger correlation between the two variables.
