INTRODUCTION

• University of Minnesota

• Simulation possibilities

• Effects of Energy Level on Memory Capabilities

• Nap Group

• Control Group

• Coffee Group

DATA SIMULATION: THE ISLAND

PARTICIPANTS AND RECRUITMENT

• Randomize Island Population

• Request Consent

• Replace Those who Denied Consent

• Randomize into Treatment Groups

• Nap Group

• Control Group

• Coffee Group

RUNNING THE EXPERIMENT

• Real Time

• Test Memory

• Treatment

• Test Memory

• Wait 30 Minutes

• Test Memory

NULL HYPOTHESIS & ALTERNATIVE HYPOTHESIS • Null: M1 = M2 = M3

• Difference 1: Memory Immediately After — Baseline Memory

• Difference 2: Memory After 30 minutes — Memory Immediately After

• Difference 3: Memory After 30 minutes — Baseline Memory

• Alternative: At least one of the groups means is different

THEORETICAL BACKGROUND:NORMALITY• Compare means One-Way ANOVA Normal

Difference 1 (Memory Immediately After — Baseline Memory) was approaching significance (p=.0839) for alpha=.05

TEST FOR NORMALITY

STATISTICAL PROCEDURES: KRUSCAL-WALLIS• Not Normal Kruscal-Wallis Test to compare means

• Compared 3 differences, no significance

• Difference 1 approaching .05 significance (p=.0927)

• Compared 2 treatment groups at a time

RESULTS: SIGNIFICANT DATA

• Out of the 15 tests run, 1 significant result

• Comparing the baseline data to the data collected immediately after intervention (Difference 1)

• The coffee group (group 3) improved significantly in the memory test compared to the control group

LIMITATIONS: WHY IS THERE NOT MORE SIGNIFICANCE?

• Memory Test Type

• Coffee Caffeine Peak and Half-Life

• Intention to Treat

• Simulation

• Population

• Program

CONCLUSION

• Normal assumption

• Test for normality, Kruscal-Wallis

• Using Minnesota’s Island simulation, drinking coffee temporarily improves memory compared to control group

• Limitations

FUTURE STUDIES

Memorize, nap, test memory

vs. Control

Previous literature

Longer wait after drinking coffee

Account for caffeine peak
