Probability: Introduction to Basic Concept
The word probability is a commonly used term that relates to the chance that a particular event will
occur when some experiment is performed. Uncertainty pervades all aspects of human endeavor.
Probability is one

Correlation
1. While dealing with data researchers very often have to come across
situation where they need to handle multiple variables simultaneously.
Under the circumstances researchers required to identify different features
of the interrelationship b

Measures of Central Tendency
Central tendency: The central tendency of a classified
data or a chart of frequency distribution can be defined as
the tendency of clustering arround of defferent values
arround a central value which is a representative of all

The summary Table
A summary table indicates the frequency, amount or percentage of items in a set of
categories so that you can see differences between the categories. A summary table
lists the categories in one column and the frequency, amount or percent

Frequency distribution
The number of times a particular value of a certain variable
occurs in a set of observations is called the frequency of
that value and the manner in which the frequencies are
distri

Measures of Dispersion
Measures of Dispersion: The degree to which
numerical data tend to spread about an average
value is called the variation or dispersion of the
data. So a description measure of scatter of the
values about the average is called measur

Probability
Definition of probability: Probability is a measure of the
chance or likelihood that a particular outcome will occur.
This occurence is measured by numerical statement assigned on a
scale 0 to 1. A probability near 0 indicates that an event is
