Lab 1 Scientific Inquiry Virtual 2022 Worksheet

The Process of Scientific Inquiry Worksheet Exercise I: Making Observations about Reaction Time Using the “Online Reaction Time Test ” Procedure You will work with the others in your breakout room. On your device, go to . Follow the instructions and take the Online Reaction Time Test. Each person in your group needs to take the test and record their individual results. Record your results to two decimal places in this table: Your Online Reaction Time Test Results Test Number Reaction Time (seconds) Spamming Reaction Time 1 .22 0.08 2 .27 0.12 3 .23 0.13 4 .24 0.04 5 .22 0.17 Average .23 0.1078 What environmental or individual differences might affect reaction times? Brainstorm with your group and record these ideas here : Fatigue , Age, caffeine intake, distractions(noise), hand eye coordination, cheating (spamming the mouse), device one is using , disability. As a group, choose one variable that you would like to test and develop a testable hypothesis. Spamming the mouse Hypothesis: If participants spam-click the button before the light turns green, then the game will record faster (lower) reaction times than when participants wait for the green light. Exercise II: Reaction Time Hypothesis and Experimental Design Hypothesis: If participants spam-click the button before the light turns green, then the game will record faster (lower) reaction times than when participants wait for the green light. Predictions (if “hypothesis is true” then “expected result”) If spam-clicking the mouse is possible, then participants who rapidly click on the “Click here on green light” button will have significantly faster reaction times compared to participants who wait for the light to turn green. Independent Variable: Clicking method (spamming vs. waiting for green light) Dependent Variable: Reaction time (seconds) Standardized variables: Device, age, video game player vs non, fatigue, disabilities, hand eye coordination, having caffeine v none Procedure (must be in sufficient detail so that it could be repeated identically by others): Open the Online Reaction Time Test game. Read the provided instructions on how to play. Position the mouse over the “Click here” button. Control group: Participants wait until the light turns green before clicking. Experimental group: Participants spam-click the mouse button in the test area before the light changes. Record the reaction time results for each participant. Repeat the test multiple times per participant and calculate the average reaction time. Compare average reaction times between the control and experimental groups. Exercise III: Gather Data from Your Classmates. Data Tables Independent variable being tested : Spamming No Spamming Spamming Control Group Experimental Treatment Group First Name of Subject Average Reaction Time (seconds) (Test Person) First Name of Subject Average Reaction Time (seconds) (Test Person) .03 Kalani .08 Kalani 0.23 Stephanine .12 Stephanine .32 Zianah .09 Zianah Hayey Hayey 0.38 Hannah .06 Hannah .31 Lilee .10 Lilee .25 Krystelle .03 Krystelle .42 Molly .38 Molly .32 .19 Ashlan .46 Ashlan .38 .23 Jim .10 Jim .30 Group Average: Group Average: .15 Exercise IV: Statistical Analysis go to http://www.graphpad.com/quickcalcs/ttest1.cfm
