2. Formulate an analysis plan
3. Analyzing the data obtained
4. Final step is to analyze the results
There are three types of variables taken in an experiment:
1. Independent variable: light, temperature, humidity
2. Dependent Variable: these depends upon the other variable. changes in the independent variable may cause the dependent variable to change, for example, growth of plant is a dependent variable which depends upon the amount of light(independent variable), the plant receives
3. Controlled Variable: these variable can be controlled and prevented from being change like ty[pe of plant, type of soil
