A sample statistic is biased if the average value of the statistic
Biased either underestimates or overestimates the corresponding
population parameter.
Central Tendency is a statistical measure to determine a single
score that defines the center of a distribution. The goal of
Central Tendency
central tendency is to find the single score that is most typical
or most representative of the entire group.
, Constructs are internal attributes or characteristics that cannot
Constructs be directly observed but are useful for describing and
explaining behaviour.
For a continuous variable, there are an infinite number of
possible values that fall between any two observed values. A
Continuous Variable
continuous variable is divisible into an infinite number of
fractional parts.
Individuals in a control condition do not receive the
experimental treatment. Instead, they either receive no
Control Condition treatment or they receive a neutral, placebo treatment. The
purpose of a control condition is to provide a baseline for
comparison with the experimental condition.
In the correlational method, two different variables are
Correlational method observed to determine whether there is a relationship between
them.
Data Data (plural) are measurements or observations.
Data Set A data set is a collection of measurements or observations.
A datum (singular) is a single measurement or observation and
Datum
is commonly called a score or raw score.
For a sample of n scores, the degrees of freedom, or df, for the
sample variances are defined as df = n - 1. The degrees of
Degrees of Freedom, or df
freedom determine the number of scores in the sample that are
independent and free to vary.
