WGU c797 TEST QUESTIONS AND ACCURATE
ANSWERS
Probability in Theory
Without gathering data, the distribution of events can be deduced.
empirical likelihood
It is necessary to assess the likelihood that each event will occur by gathering
data.
Because probability measures the exact likelihood that an event will occur, it
offers a numerical measure of uncertainty.
Descriptive statistics are numerical data that quantify and characterize group
attributes.
Inferential statistics are numerical data that let one determine the likelihood that
a population's characteristics are true based on sample data.
mean
The mean of a collection of figures
Half of the scores are above the median, which is the midpoint score of a
distribution.
Mode
the value in a given data set that appears the most frequently.
range is the distinction between a distribution's highest and lowest scores.
