ASM MIDTERM REVIEW QUESTIONS AND
ANSWERS
qualitative data - ANSWER Information describing colour, odour, shape, or
another physical feature
ANSWER: numerical data.
A prediction is a statement of the predicted outcomes of an experiment based on
the hypothesis being investigated.
In an experiment, the independent variable is the variable that is being modified.
In an experiment, the variable being measured is referred to as the dependent
variable.
Control variables are factors that are not being tested but must remain constant in
case they affect the experiment.
confounding variable - ANSWER in an experiment, a factor other than the
independent variable that may cause an effect
A water bath is a container of water heated to a specific temperature and used to
heat things placed in smaller containers.
Buffer is a weak acid or base that can react with strong acids or bases to assist
prevent dramatic, unexpected changes in pH.
Reliable - Results that can be duplicated by others.
, An anomaly is a result or observation that differs from what is typical or expected.
Precision is a measure of how near a set of measurements are to one another.
Accuracy - Answer. A description of how closely a measurement corresponds to
the true value of the quantity measured.
A continuous variable is a quantitative variable with an endless number of possible
values that cannot be counted.
discontinuous variable - ANSWER is counts and categorical data, which must be
whole numbers.In a *Bar Graph* with discontinuous data, the bars do not intersect.
Category or color data are examples of discontinuous variables.
systemic error - ANSWER error coming from a faulty part of the research design
that produces a responder error or a mistake in the conduct of the research.
Random Error - Answer Error that occurs by chance and is not standardized.
Decreases precision.
Proton - Answer A positively charged subatomic particle contained in an atom's
nucleus.
Neutron - ANSWER A chargeless subatomic particle found in an atom's nucleus.
Electron - Answer A negatively charged subatomic particle.
