| A | B |
|---|
| Independent Variable | The variable that I change in the experimental groups |
| Dependent Variable | The variable that reacts or responds to the experiment |
| Controlled variables | All the variables you want to keep the same in the experiment between the groups |
| Bias | Your thoughts and feelings toward something |
| How do you get rid of Bias? | By other researchers repeating your experiment |
| Operational Definition | Explain EXACTLY how you will change the independent Variable and measure the dependent variable |
| Qualitative Data | Data that describes the qualities in words like texture, color, smell, appearance |
| Quantitative Data | Data that tells the quantity or number of something. |
| Hypothesis | Your guess in if, then format about the outcome of your question |
| Question | Drives or leads the experiment- all the steps depend on this. |
| Trends in Graphs | The relationship between the variables on the 2 sides of the graph. "When x does this, then Y does that." The story your graph is telling. |
| X axis on the graph | Line (or axis)on the bottom and goes across. Has the INdependent variable here. |
| Y axis on the graph | Line on the side (or axis) going up. Has the Dependent variable here. |
| The variable after the "If.....," in the hypothesis | INdependent Variable |
| The variable after the "then........" in the hypothesis | Dependent variable |
| Pick out the Independent variable in the hypothesis: If different materials of canvas, nylon, and cotton are used to make a backpacks, then the canvas will hold the most weight. | Different materials of canvas, nylon, and cotton |
| Pick out the Dependent variable in the hypothesis: If different materials of canvas, nylon, and cotton are used to make a backpacks, then the canvas will hold the most weight. | weight able to be held by backpack |
| What are controlled variables in the experiment with the hypothesis: If different materials of canvas, nylon, and cotton are used to make a backpacks, then the canvas will hold the most weight. | Same size backpack, same stictching, same thread type, same movement of the backpack for tests |
| If you have a totally complete set of data- Like a video of Ms. Bercz walking down the hall, how many good conclusions for number of steps can you come up with? | ONE |
| If you have an incomplete set of data, Like Ms. Bercz walking down the hall and going out of view for 5 minutes and then stepping back in. How many different good conclusions can you come up with for number of steps taken? | More than one |
| What is the independent variable in the hypothesis: If dogs are fed different types of dog foods, then the dogs fed Iams will be the healthiest. | Different foods |
| What is the dependent variable in the hypothesis: If dogs are fed different types of dog foods, then the dogs fed Iams will be the healthiest. | Health of the dog |
| What are controlled variables in the hypothesis (experiment): If dogs are fed different types of dog foods, then the dogs fed Iams will be the healthiest. | same amount of water, same environment, same temperature, same amount of attention, same amount of grooming |
