These are variables that are kept the same throughout the experiment.
What are control variables?
100
These three summary statistics are helpful in analyzing quantitative data.
What are mean, median, and mode?
100
This is what you use to draw your conclusions.
What is data?
100
This is the purpose of the scientific method.
What is to find answers to questions?
200
The experiment is designed to answer this.
What is the question?
200
This variable is thought to have an effect on the outcome.
What is the independent variable?
200
When graphing data, this variable is graphed on the x-axis.
What is the independent variable?
200
You should reference this statement from earlier in the lab as you begin your conclusion paragraph.
What is the hypothesis?
200
The scientific method can follow more of this path than a linear one.
What is circular or looping?
300
All hypotheses should be in this format.
What is "if, then."
300
In some experiments, these two groups are designed so the scientist can compare receiving the independent variable and not receiving it.
What are control and experimental groups.
300
When collecting and analyzing qualitative data, this is helpful in organizing the data?
What is a table or chart?
300
A hypothesis is either ___ or ____, but never correct, wrong, true, or right.
What is supported or not supported?
300
These are three ways that scientists publish their work.
What is writing in peer-reviewed journals, presenting at conferences, and contacting the media?
400
A possible hypothesis for the question, "Is there more humidity in the air a day before it rains or a day after it rains?"
What is (several possible answers).
400
A reason why it is important for the scientist to identify the independent and dependent variables when planning an experiment.
What is (several possible answers)
400
In analyzing data that is collected from an experimental group and a control group, it could be helpful to find this change if using quantitative data.
What is percent change?
400
This part of the conclusion discusses any part of the experiment that could not be controlled or could inadvertently affect the results.
What is the sources of error?
400
This is when your quiz is.
What is tomorrow?
500
This step is sometimes left out in school labs, but it helps the scientist focus his/her experiment and better understand what scientists already know about the topic.
What is research?
500
The flaw in an experiment in which the scientist is testing the effect of organic dog food on puppy weight gain. Two pups from the same litter are selected. The male pup receives the organic food, and the female pup receives the conventional food.
What is not controlling all the variables (in this case, gender)?
500
In one group of the heart rate and caffeine experiment, you collect the following heart rates:
57, 70, 81, 74, 61, 84, 76, 64, 72, and 69.
This is the average of this data.
What is 70.8 or 71?
500
You observe a teacher drinking coffee, and you wonder about the effects of caffeine on heart rate. You think that if a person drinks caffienated beverages, then the person's heart rate will be higher. You conduct an experiment, and your results show that average heart rate for non-caffeine drinkers was 75 and average heart rate for caffeine drinkers was 84, this could be your conclusion.
What is (many possible answers).
500
These are three characteristics of the scientific method.
