QUESTIONS AND CORRECTLY WELL
DEFINED ANSWERS LATEST 2025 - 2026
ALREADY GRADED A+
Continuous Random Variable - ANSWERS-a random variable
that may assume any numerical value in an interval or
collection of intervals
Probabilty Distribution - ANSWERS-A description of how the
probabilities are distributed over the values of a random
variable.
Probability Function - ANSWERS-a function, denoted by f(x),
that provides the probability that x assumes a particular
value for a discrete random variable
,Empirical Discrete Distribution - ANSWERS-a discrete
probability distribution for which the relative frequency
method is used to assign the probabilities
Discrete Uniform Probability Distribution - ANSWERS-a
probability distribution for which each possible value of the
random variable has the same probability
Expected Value - ANSWERS-A measure of the central
location, or mean, of a random variable.
Data Mining - ANSWERS-The process of using procedures
from statistics and computer science to extract useful
information from extremely large databases.
Frequency Distribution - ANSWERS-A tabular summary of
data showing the number (frequency) of observations in
each of several nonoverlapping categories or classes.
Relative Frequency Distribution - ANSWERS-A tabular
summary of data showing the fraction or proportion of
observations in each of several nonoverlapping categories
or classes.
, Percent Frequency Distribution - ANSWERS-A tabular
summary of data showing the percentage of observations in
each of several nonoverlapping classes.
Bar Chart - ANSWERS-A graphical device for depicting
categorical data that have been summarized in a frequency,
relative frequency, or percent frequency distribution.
Pie Chart - ANSWERS-A graphical device for presenting data
summaries based on subdivision of a circle into sectors that
correspond to the relative frequency for each class.
Class Midpoint - ANSWERS-the value halfway between the
lower and upper class limits
Dot Plot - ANSWERS-a graphical device that summarizes
data by the number of dots above each data value on the
horizontal axis
Histogram - ANSWERS-A graphical display of a frequency
distribution, relative frequency distribution, or percent
frequency distribution of quantitative data constructed by
placing the class intervals on the horizontal axis and the
