What are the steps of the scientific method?
There are different steps to follow in a scientific method
- Definition and problem statement. The question for which there is no answer yet. A question the investigator wants to answer.
- Goal specification. The goal is what the investigator wants to know.
- Hypothesis formulation. The researcher hypothesizes in order to predict what is going on or what is expected to occur.
- Experiment. Different variables influencing the project are considered. This step involves testing the observations. Data collection and analysis stages.
- Discussion and hypothesis verification. This step involves the deriving of the working hypothesis.
The followings are related specially to the experimental part,
A- Measure the variables
B- Take a random sample
C- Create your operational definitions
D- Conduct statistical evaluation
E- Identify the variables
F- Identify the sampling universe
G- Determine weather your results are statistically significant
Correct order and explanation,
E- Identify the variables
This is the first thing to be done before the experimental procedure. You need to know which are you independent, dependent, and controlled variables.
F- Identify the sampling universe
The sampling universe refers to the population from which you are choosing your sample.
B- Take a random sample
We talk about random samples because you should not make a selection of individuals. They should be randomly taken from the population to be more representative and show no tendency.
C- Create your operational definitions
The term operational definition refers to how you are taking your measures. You need to determine how to collect data before doing it. This stage needs to be detailed and well described to get consistent results and to be replicated by other reseachers.
A- Measure the variables
At this point you take your measures using your sample and according to the operational definitions.
D- Conduct statistical evaluation
Once you get data from measures, you will conduct statistical evaluation to make it reliable.
G- Determine weather your results are statistically significant
You will do it according to the significance level.
The correct order is E, F, B, C, A, D, G
