Scientific Method Flashcards
Scientific Investigations
Observations, surveys, trial and error, case studies
Experimental Variables
Independent variable, dependent variable, controlled variable
Independent variable
Factor being changed/manipulated
Dependent variable
Factor being measured
Controlled Variable(s)
Factors in an experiment that is kept equal
Validity
Results obtained are due to the effect of the indipendent variable
Reliability
Results obtained are considered a true representation of the true value
Hypotheses
Single, Testable statement
Quantitative Data
Measurements of observations
Qualitative Data
Comaprison of Observations
Title
Mentions both variables
Axes
What is being measured and their units
Systemetic Error
Consistently positive / negative (faulty equitment)
Random Error
Equally likely to be positive or negative
Accuracy
How close measurements are to true value
