●● Descriptive Analytics
Answer: Analytical techniques that describe what has happened in the
past.
●● Predictive Analytics
Answer: Analytical techniques that use models constructed from past
data to predict the future or assess the impact of one variable on another.
●● Prescriptive Analytics
Answer: Analytical techniques that yield a course of action.
●● Big Data
Answer: 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
Answer: The process of using procedures from statistics and computer
science to extract useful information from extremely large databases.
,●● Frequency Distribution
Answer: A tabular summary of data showing the number (frequency) of
observations in each of several nonoverlapping categories or classes.
●● Relative Frequency Distribution
Answer: A tabular summary of data showing the fraction or proportion
of observations in each of several nonoverlapping categories or classes.
●● Percent Frequency Distribution
Answer: A tabular summary of data showing the percentage of
observations in each of several nonoverlapping classes.
●● Bar Chart
Answer: A graphical device for depicting categorical data that have been
summarized in a frequency, relative frequency, or percent frequency
distribution.
●● Pie Chart
Answer: 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
, Answer: the value halfway between the lower and upper class limits
●● Dot Plot
Answer: a graphical device that summarizes data by the number of dots
above each data value on the horizontal axis
●● Histogram
Answer: 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
Answer: 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.
●● Cumulative Relative Frequency Distribution
Answer: A tabular summary of quantitative data showing the fraction or
proportion of data values that are less than or equal to the upper class
limit of each class.
●● Cumulative Percent Frequency Distribution
