Hypothesis
McGuigan
"Hypothesis is testable statement of a potential relationship between two or more variables".
"A strategy adopted in order to solve some problem".
"A strategy adopted in order to solve some problem".
Kinds of Hypothesis
1. Scientific Hypothesis
Scientific hypothesis represents the predicted relationship among the variables being investigated.
2. Null Hypothesis
The null hypothesis represents a statement of no relationship among the two or more variables being investigated.
For example____Someone wanted to explore the nature of the memory deficits that occur through the influence of alcohol.In scientific hypothesis the relationship between alcohol and memory is a factual event.When intoxicated individual would fail to recall meaningful content during the taking of alcohol.But in same circumstances the null hypothesis insist that it makes no difference at all.The meaningful content recall even who have approached alcohol or who did not do so.Null hypothesis rejects that there is relationship between alcohol and memory recall.

With the above reference of the headings first of all the question is this that where do ideas or problems originate?
Where should we look for a researchable problem?
In all fields of life there are a number of common sources of problems such asWhere should we look for a researchable problem?
A. Existing Theories
B. Past Research
Being a student of psychology or being a social scientist or psychologist, we are formulated that we draw so much from everyday life .The things we___________Read about, See about, Hear about.
If you ask the question "why" you will find many researchable topics.
There are only four sources.
1. Theory
2. Everyday Life
3. Practical Issues
4. Past Research
Now we will discuss the four sources in detail.
1. Theory
A theory defined as "A group of logically organized laws"(Marx)
Theory is of two type functions.According to Marx
1. Tool Function Theory
2. Goal Function Theory
The tool function is evidenced by the proportions that theories guide research.
The goal function is that laws are ordered and integrated by theories; Theories summarizes and integrate existing knowledge.
2. Everyday Life
As we proceed through the daily routine dictated by our current point in life, we come into contact with many phenomena that pose questions in need of solution.
Parents want to know how to handle their children , students want to know how to learn material faster.When we interact with others or see others react, we note many individual differences.When one is observing children on a play ground, these differences are readily apparent, one child may be very aggressive, while an other is much more reserved, waiting for others to encourage interaction.The response of a particular person also vary according to the situation.A child who is very aggressive in one situation may be very passive in another.why do these differences exist not only among children but also within the same child.
What produces these varying responses?
Why are some people leader and other followers?
Why do we like some people and not others?
These are many researchable questions that can be identified from the interactions and personal experiences that every one has.
3. Practical Issues
Many experimental problems arise from practical issues that require solutions.
Private industry faces problems such as employee moral, absenteeism, turnover, selection and placement to name only a few. Counseling and clinical psychology is the need of a great deal of research to identify more efficient modes of dealing with mental disturbances. Units of the federal and provincial governments also support experimentation designed to solve practical problems. The government is spending large sum of money to find a cure for Cancer, Hepatitis, TB, Drug-addiction and so many such an other problems. Large expenditures are also being directed toward finding better ways to conduct the educational process.
Grievous crimes such as Kidnapping, Murder, Rape, Smuggling the young children for Camel Race are required such a measure that if not these have been stopped but should be minimized in any situation.
Above mention all are practical concerns required solution.
4. Past Research
Previously conducted research/experiments are an excellent source of research ideas.Each well-designed study does provide additional knowledge, phenomena are multi-determined.In any experiment only a limited number of variables can be studied.Investigation of certain variables may lead to hypothesis about the effects of other variables.

thanks for telling us about hypothesis ans its types! what is you favorite color? http://skywritingservice.com/blog/impact-of-color-psychology-on-us shows how colors can change our mood!
