SLO2: Apply scientific method to laboratory investigations including designing experiments and interpreting quantitative information using graphs. Observation: A group of tutors observed that some students use their cell phones for off-task like texting and social media while studying (the “multi-taskers”) but other students do not use their cell phones while studying (the the single-taskers) Question: Is there a difference in test scores between the multi- taskers and the single-taskers? Experiment Design (5 questions, 1 point each 5 points total) 1. What is your hypothesis? 2. What 2 groups are being compared? 3. What is the independent variable? 4. What is the dependent variable? 5. Identify a control variable: Data analysis (2 questions, 2.5 points each 5 points total) The test results were as follows: Student Type (10 students total) Multi-tasker Multi-tasker Test Score out of 100 93 71 61 Single-tasker 82 79 84 52 90 81 Single-tasker Multi-tasker Multi-tasker Multi-tasker Single-tasker Single-tasker The average test score for the multi-taskers was: 75.8/100 The average test score for the single-taskers was: 80.4/100 1. Create a graph to indicate the results of the experiment. 2. Write a one sentence in your graph.
