Presentation And Analysis Of Business Data 1 Flashcards
It is a factual information in a raw or unorganized form.
Data
This involves categorical measurement expressed not in numbers but through a
natural language description.
Qualitative Data
This involves information about quantities that can be measured and written
down with numbers.
Quantitative Data
Is the branch of mathematics that focuses on collecting, organizing, analyzing, and interpreting
data.
Statistics
Data can be gathered from either:
Primary sources
Secondary sources
The person doing the research gathers the data him/herself.
Primary sources
The person doing the research uses data gathered by somebody
Secondary sources
It is mutually exclusive and exhaustive and is used to
differentiate classes or categories for pure classification or identification purposes.
Nominal
is a property of a set of categories such that an individual or object is
included in only one (1) category.
Mutually exclusive
is a property of a set of categories such that an individual or object must appear in a category.
Exhaustive
It is used in ranking. It is somewhat a stronger form of
measurement because an observed value classified into one (1) category is said to possess more of
a property being scaled than does an observed value classified into another category.
Ordinal
It is used to classify order and differentiate between classes or
categories in terms of degrees or differences._____ data are either discrete or continuous variables.
Interval
It differs from interval measurement in only one aspect, with a true
zero (0) point (absolute value of zero).
Ratio
It is a set of facts or figures systematically displayed or organized, especially in columns.
Table
are easily
constructed using the Word processor’s table function or a spreadsheet program like Excel.
Tables
The following are the different parts of a table:
Table number.
Title
Head note
Stubs or Row headings
Body of the table.
Source note
Footnote.
It is the first item mentioned at the top of each table for easy identification and
reference.
Table number
It is the second item that is shown just above the table. It narrates the contents of the table. Hence it has to be very clear, brief, and carefully worded.
Title
At the top of each column in a table, a column designation/head is given to explain the figures of the column. This column heading is known as “caption.”
Headnote
The title of the horizontal rows is known as “____.”
Stubs or Row heading
It contains numeric information and reveals the whole story of investigated facts. Columns are read vertically from top to bottom, and rows are read horizontally from left to right.
Body of the table
It explains the specific feature of the table, which is not self-explanatory and has not been
explained earlier. For example, points of exception, if any.
Footnote
It is a brief statement or phrase indicating the data source presented in the table
Source note
is the grouping of data into categories showing the number of observations in each non-overlapping class
Frequency Distribution
It is the data collected in original form.
Raw data
t is the difference between the highest and lowest values in a distribution.
Range
It is the highest and lowest value describing a class
Class limits
It is the upper and lower values of a class or group frequency distribution.
Class boundaries
The following are the two (2) types of frequency distribution:
Categorical Frequency Distribution
Grouped Frequency Distribution
It is used to organize qualitative data.
Categorical Frequency Distribution
It is used to organize quantitative data. Data must be grouped into
classes; class intervals must be determined.
Grouped Frequency Distribution
