Experiment Basics: Variables: Transcript


Psych 231 Research Methods in Psychology Class Experiment Class Experiment Print out the Class experiment listed on syllabus page exercise and bring it to labs this week Turn in your data sheets pass to front. Setups of an experiment should have only one variable that is changed at a time By having only one variable that is changed you can be fairly cert ain that the results of the experime nt were caused by that one variable Three types of variable s are Experimental Design. From Hypotheses to Conclusions. Learning . Target #1. (Write it down. ). I can understand and identify independent variables, dependent variables, constants, and controls.. Journal Question. Start a New Page. Add to your Table of Contents (TOC). 1. Learning Target. (Write it down. ). Learning Target: I can understand and identify independent variables, dependent variables, constants, and controls.. Observational Method. Experimental Method. Experimental Design. Aims & Hypothesis . Variables: IV, VD & EV/CV . Operationalisation. . Sampling Techniques. Factors Associated with Research Design . Collecting Data Sensibly. 2.1 Statistical Studies: Observation and Experimentation. Whether or not a conclusion is reasonable depends on how the data were collected.. Sometimes we’re are interested in answering questions about the characteristics of a single population or in in comparing two or more well defined populations.. Complete a level-up quiz. If you finish early, study for your next quiz.. Questions about hindsight bias or overconfidence?. Research Methods . Theory vs. Hypothesis. Theory. : An explanation of events or behaviors based on a series of observations OR scientific findings. . Find your table/seat assignment. Introduce yourself to your neighbors. As a group define the scientific word . (green tent) left on your table – write your. groups definitions on the white paper with the dry erase marker.. Internal Assessment. Criterion A: . Introduction, 5 marks, 3.6% of IB Grade . Criterion B: . Method: Design, 2 marks, 1.4% of IB Grade . Criterion C: . Method: Participants, 2 marks, 1.4% of IB Grade . 1st Paper Airplane: notebook paper. 2nd Paper Airplane: printer paper. 3rd Paper Airplane: construction paper. 4th Paper Airplane: Tissue paper. . Identify the manipulated variable (independent variable) in this experiment.. Science Fair Preparation. Testable Question . A question that asks how one change (independent variable) has a measureable effect on something else (dependent variable). . Testable Question . Does changing the height of the ramp affect the speed of a car going down the ramp?. 1st Paper Airplane: notebook paper. 2nd Paper Airplane: printer paper. 3rd Paper Airplane: construction paper. 4th Paper Airplane: Tissue paper. . Identify the manipulated variable (independent variable) in this experiment.. What does it mean for something to . vary. ?. What does the word . dependent . mean?. Imagine you are creating an experiment to test your hypothesis that tomatoes grow better with fertilizer. What are some steps you would take?. Variables. Variables. are . parts of an experiment. . that . can be changed or controlled.. Independent variable. The variable that is manipulated, chosen to be observed, or purposefully changed. . What is Statistics?. The science of collecting, organizing, and interpreting numerical facts, which we call data. Data (def.) – the numbers or information collected in a study or experiment.. How is collect data.
