What is the first step of the Scientific Method?
Observation
The Scientific Method starts with making an observation about the natural world.
What are the two categories of data?
- Qualitative
- Quantitative
What is qualitative data?
Descriptions such as names, senses, and cannot be zero
Examples include color descriptions, textures, and other sensory details.
What is quantitative data?
Numbers such as recorded measurements, can be zero
Examples include height, weight, and temperature.
Define hypothesis.
A proposition that makes predictions and is testable.
What is a theory?
A broad explanation backed by lots of evidence.
What happens if the hypothesis is rejected?
A new revised hypothesis is made.
What is the goal of Discovery Based Science?
To gather more information without a preconceived hypothesis.
List the five stages of the Scientific Method.
- Observations
- Hypothesis Formation
- Experimentation
- Data analysis
- Conclusion
What defines a Control Group?
A group that is controlled and has no variables.
What is an Experimental Group?
A group with a small difference to test the hypothesis.
What is an independent variable?
What you are changing in your experiment.
What is a dependent variable?
The variable of interest that is affected by the independent variable.
Fill in the blank: A ________ proposes that no statistical significance exists among a given set of observations.

What does Standard Deviation measure?
The dispersion of values from the average value.
What is the purpose of the Student T-test?
To determine how true the calculated mean and standard deviation are according to the population.
What does the P-value represent?
The probability that the results in your sample occur by chance.
True or False: Statistical significance means the outcome of the experiment is due to chance alone.
False
What is a population in statistical terms?
The entire set of items that you are interested in.
What is a sample?
A portion of the population.
What is required to perform a T-test?
- Mean of your 2 groups
- Standard Deviation/error of the Groups
- N, or Sample number for each group
