EVALUATION TESTED QUESTIONS WITH
DETAILED SOLUTIONS
●● Hypothesis
Answer: An explanation of an observation that can be tested through
experimentation.
●● Variable
Answer: A condition in an experiment that can be controlled or changed.
●● Theory
Answer: A well substantiated explanation of an aspect of the natural
world that has been repeatedly tested and confirmed through observation
and experimentation.
●● Refute
Answer: submitting evidence that shows that a hypothesis is not correct.
●● Qualitative Data
Answer: descriptive data about a variable
,●● Quantitative Data
Answer: numerical data that give the quantity, amount or range of a
variable
●● Prediction
Answer: a statement of the expected results in an experiment based on
the hypothesis being tested
●● Independent variables
Answer: the variable being changed in an experiment (changed by the
scientist)
●● Dependent variables
Answer: the variable being measured in an experiment (changes in
response to a change in the independent variable)
●● Control Group
Answer: a group within an experiment or study that receives exactly the
same treatment as the experimental group with the exception of the
variable being tested.
●● Control variables
Answer: variables that are not being tested but that must be kept the
same in case they affect the experiment
, ●● Confounding variables
Answer: a variable that could affect the dependent variable. In
laboratory experiments these are the variables that must be controlled. In
field experiments they are normally just measured and recorded
●● Reliable
Answer: results that can be replicated by other people
●● Anomaly
Answer: a result or observation that deviates from what is normal or
expected. In experimental results it normally refers to one repeated
results that does not fit the pattern of the others.
●● Parasitism
Answer: a relationship between two organisms where one obtains
benefit at the expense of the other
●● Competition
Answer: a relationship between two organisms were both species are
negatively affected by trying to feel the same ecological niche
●● Predation
