Scientific Method
The scientific method is the basis of scientific investigation. A scientist will pose a question and formulate a hypothesis as a potential explanation or answer to the question. The hypothesis will be tested through a series of experiments. The results of the experiments will either prove or disprove the hypothesis. This category should contain questions and answers regarding the scientific method.

What are the stages in an experiment?
The basis steps of an experiment are :
- Defining the phenomenon
- Forming a hypothesis
- Designing an experiment
- Performing and Observing the experiment
- Analyzing the data
- Stating and Publishing the Conclusions
Another version of the same steps is :
1) General Question
2) Narrowing Down
3) Designing the Experiment
4) Observation
5) Analysis
6) Conclusion
In some experiments, the analysis may determine that no conclusion is possible. The sixth step would be to try to identify possible flaws in the experimental procedure, so that they might be corrected if the experiment is to be repeated.
Can you make a inference without having made any observation?
Yes, that is what is called a blind guess.
yes
Will a light bulb evaporate water?
If you were to put a bare wire belonging to anything in a glass of water, the electricity flowing through the wire would have no reason to continue to travel through the wire instead of dispersing in the water.
The water offers less resistance, so the electricity flows through that instead of the wire. This is known as creating a short circuit, or a short, for short! With no electricity flowing through the bulb, it will turn off.

Advantages of the step method of cost allocation?
Advantages:
- Considers some of the interdependence of service departments
Disadvantages:

- Allocation less than opportunity cost for first department
- Allocation more than opportunity cost for last department
What step gives an investigation a specific direction or focus?
A Hypothesis gives an investigation a specific direction or focus.
Is a cross sectional study quantitative or qualitative study?
Cross-sectional study can be either qualitative or quantitative or mix method, Cross-sectional surveys are used to gather information on a population at a single point in time. An example of a cross sectional survey would be a questionaire that collects data on how parents feel about Internet filtering, as of March of 1999. A different cross-sectional survey questionnaire might try to determine the relationship between two factors, like religiousness of parents and views on Internet filtering.
- Takes place at a single point in time
- Does not involve manipulating variables
- Allows researchers to look at numerous things at once (age, income, gender)
- Often used to look at the prevalence of something in a given population.
