The document discusses the concept of data, defining it as collections of facts or information used for deriving conclusions. It categorizes data into quantitative and qualitative types, with quantitative data further divided into discrete and continuous data, and qualitative data into nominal and ordinal data. Each type of data is characterized by its nature, measurement, and organizational structure.

DATA  Data can be defined as a collection of facts or information from which conclusion may be drawn.  Data are measurement or observation that are collected as a source of information.  Data is a set of values of subjects with respect to qualitative or quantitative data.  We use data to be able to gather information for reference or analysis.
TYPES OF DATA
QUANTITATIVE DATA  Quantitative data consist of values representing counts or measurement.  Quantitative data are data about numeric variables.  Also called numerical data.  Quantitative ---> Quantity
TYPES OF QUANTITATIVE DATA DISCRETE  Discrete data is one that has clear spaces between values.  Discrete data is countable.  Discrete data usually involve counting a number of items, such as the number of book, computer, people, etc.
CONTINUOUS DATA  Continuous data is measured. Continuous data can take on any value as it’s measured.  It is called continuous because it can take the form of continuing numerical readings (decimal values).
QUALITATATIVE DATA  Qualitative data is defined as the data that approximates and characterizes.  Qualitative data is non- numerical in nature.  Qualitative data is also called categorical data since this data can be grouped according to categories.
TYPES OF QUALITATIVE DATA NORMINAL DATA  Nominal data is a type of data that is used to label variables without providing any quantitative value.  Nominal data can be counted but not put in ascending or descending order (sorted).  It is the simplest form of a scale of measure.
ORDINAL DATA  Ordinal data are the type of data in which the data values follow a natural order.  Ordinal data is data which is placed into some kind of order or scale.  You can count and order ordinal data, but it cannot be measured like numerical data.
