Elements Common to Most Experiments |
1. Treatment 2. Experimental Group 3. Control Group 4. Variables |
|
|
Blind Experiment Design |
The experimental subjects do not know which treatment (if any) they are receiving |
|
|
Double-Blind Experimental Design |
Neither the experimental subjects nor the experimenter knows which treatment the subject is receiving |
|
|
Randomized |
The subjects are randomly assigned into experimental and control groups |
|
|
Positive correlation |
Meaning that when one variable increases, so does the other |
|
|
Negative Correlation |
Meaning that when one variable increases, the other doesn't. |
|
|
Pseudoscience |
Individuals make scientific-sounding claims that are not supported by trustworthy, methodical scientific studies |
|
|
Anecdotal Observations |
Based on only one of a few observations |
|
|
Evolution + Example |
- A genetic Change in the population - A diverse population does down - Example: Fruit Flies that can stay alive longer even with starvation in play |
|
|
Natural Selection |
The consequence of certain individual organisms in a population being born with characteristics that enable them to survive better and reproduce more than the offspring of other individuals in the population |
