Document Summary
This first thing you do before you can make a hypothesis is observe. Explanation is answering why something is going to happen. Prediction is answering when this will happen, cause and effect, what causes something to happen, asking questions. Control/influence is changing the conditions of the environment. Spontaneous patterns of natural behavior but in lab. Have to wait for an event to happen. May be inclined to over act due to audience observing. Hypothesis start with operational definition, general topic or idea with same. Manipulation independent variable the one you manipulate. Dependent variable the one that you measure/record. But what if the control and experimental groups are not the same? bias, random selection, random assignment, chances are lowered. Limitation selection bias selecting control groups for selection bias eliminate. Placebo effect positive response to treatment due to expectations. Nocebo effect negative effect, negative physical response because you. Experimental bias, subtle but influencing believe it is negative.
