| A | B |
|---|
| problem statement | question being asked |
| fair test | a clear cause/effect relationship determined; reason for many constants |
| research | collecting information to make a hypothesis |
| hypothesis | a prediction about the relationship between the IV and the DV |
| variable | any factor that could effect the results of the experiment |
| independent variable | changed on purpose by the investigator |
| dependent variable | measured as a result of the change in the independent variable |
| constants | variables kept the same to ensure the experiment is fair |
| data | #'s or observations collected during an experiment |
| x axis | labeled with my independent variable |
| y axis | labeled with my dependent variable |
| independent | not influenced by any other factor |
| experiment | test performed to see if data supports hypothesis |
| control group | used to compare my independent variable |
| data tables/charts | organizational tools for experimental information |
| conclusion | summary of the experiment that analyzes the results |
| multiple trials | repeat the experiment to make sure results are accurate |
| inference | a person's own interpretation of observations |
| procedure | what to do, how to do it and in what order |
| observations | using senses or measurements |
| model | a representation of a real item or event that has shared characteristics |
| quantitative data | observations in numerical form (ex. 14 cm or 399 km/hr) |
| qualitative data | observations of features such as color (blue), texture (smooth), shape (jagged); i.e. no numbers |
