UCF QMB3200 Midterm Study Questions
and Answers
Analytics
Ans: the scientific process of transforming data into insight for making
better decisions
Descriptive Analytics
Ans: Analytical techniques that describe what has happened in the past.
Predictive Analytics
Ans: Analytical techniques that use models constructed from past data
to predict the future or assess the impact of one variable on another.
Prescriptive Analytics
Ans: Analytical techniques that yield a course of action.
Big Data
Ans: A set of data that cannot be managed, processed, or analyzed with
commonly available software in a reasonable amount of time. Big Data
are characterized by 4 v's: volume, velocity, variety, and veracity.
Data Mining
Ans: The process of using procedures from statistics and computer
science to extract useful information from extremely large databases.
Frequency Distribution
Ans: A tabular summary of data showing the number (frequency) of
observations in each of several nonoverlapping categories or classes.

Ans: A tabular summary of data showing the fraction or proportion of
observations in each of several nonoverlapping categories or classes.
Percent Frequency Distribution
Ans: A tabular summary of data showing the percentage of observations
in each of several nonoverlapping classes.
Bar Chart
Ans: A graphical device for depicting categorical data that have been
summarized in a frequency, relative frequency, or percent frequency
distribution.
Pie Chart
Ans: 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
Ans: the value halfway between the lower and upper class limits
Dot Plot
Ans: a graphical device that summarizes data by the number of dots
above each data value on the horizontal axis
Histogram
Ans: 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
frequencies, relative frequencies, or percent frequencies on the vertical
axis.
Cumulative Frequency Distribution
Ans: A tabular summary of quantitative data showing the number of
data values that are less than or equal to the upper class limit of each
class.
