Variables
Is anything that can take on differing or varying values. The values can differ at various times for the same object or person, or at the same time for different objects or persons.

determine if relationships exist between variables. Multivariable relationships involve at least two independentvariables and the effect they have on a dependentvariable. The independentvariables must have a distinct and measurable effect on the dependentvariable or there is no relationship. The given...

the variance in an interval dependent, based on linear
combinations of interval, dichotomous, or dummy independentvariables. Multiple regression can establish that a set of
independentvariables explains a proportion of the variance in a
dependentvariable at a significant level (through a...
hypothesis is a statement about two variables, independent and dependent, and their relationship with an expected outcome based on the research question which, if directional, will state the expected direction of the relationship between the independent and dependentvariables. If the research hypothesis is...
shareholder value using governance and performance data from a sample of 15 companies listed on the Uganda Securities Exchange.
Four (4) independentvariables; the size of the board of directors, independence of the board, tenure for CEO’s and the size of the audit committees were regressed against...
“Does a linear relationship exist between the dependentvariable and the independentvariables. Based on the multiple regression model of the Virginia hospitals data, all of the independentvariables are not significant predictors of the dependentvariable. This is evidenced by the varying p-values shown...

categories should be provided for all
subjects or objects or response.
• Categories should be mutually exclusive
and independent – there should be no
overlap between the categories, to ensure
that a subject or response can be placed in
only one category.

ways:
a) Null Hypothesis (H0): The consumer satisfaction is dependent only on five factors namely, price, taste, quantity, ambience and hygiene.
b) Alternative Hypothesis (H1): The consumer satisfaction is not only dependent on the five factors namely, price, taste, quantity, ambience and...
This report is based on a small scale survey conducted on parents of kindergarten children. It focuses on their income level; how income varies with variable factors such as job type (business or service-holder, gender (female or male), job position (rank in job sector), age, education level (no. of years...

Dependentvariable – Yield per hectare...
components. Linear Regression is a statistical technique that correlates the change in a variable to other variable/s, the representation of the relationship is called the linear regression model.
Variables are measurements of occurrences of a recurring event taken at regular intervals or measurements...

Recall
Dependent and Independentvariables?
Example 1
Consider an equation y = 4 x + 1
The values of y depend on the choice of x.
y - dependentvariable (function)
x - independentvariable (argument)
Example 2
For a parametric equations of...

Regression and correlation analysis:
Regression analysis involves identifying the relationship between a dependentvariable and one or more independentvariables. A model of the relationship is hypothesized, and estimates of the parameter values are used to develop an estimated regression...
used when there are two or more dependentvariables. It helps to answer : 1. do changes in the independentvariable(s) have significant effects on the dependentvariables; 2. what are the interactions among the dependentvariables and 3. among the independentvariables.[1]

Example of Motivation as Independentvariable:
“At a call centre, quality of solution provided to a inbound customer is dependent on the level of
motivation & know how of the call centre employee responding to the call”
Dependentvariable - Quality...
analyzing several variables, when the focus is on the relationship between a dependentvariable and one or more independent. More specifically, regression analysis helps one understand how the typical value of the dependentvariable changes when any one of the independentvariables is varied, while the...
it measures the separation of two points.
DependentVariable
When two variables are related, we say that one depends on the other. This variable is called the dependentvariable. The"other" variable is free to roam so it is called the independentvariable. In a scientific experiment, the experimenter...
connections between variables which is important in any problem situation.
Variable is anything that can take on differing or varying values. In this case study, there are 2 types of variables. Firstly known as the dependentvariables, this is also known as the criterion variable. The second one is...
data can be used to anticipate the effect of several variables. Multivariate relationships involve multiple independentvariables affecting a dependentvariable. These independentvariables have a distinct and measurable effect on the dependentvariable. These relationships can be used by managers to make...
