can you please help me to answer this questions
2. Answer the following questions based experiment:
a. What were the independent and dependent variables?
b. What was/were the controlled variable(s)?
c. How was the experiment replicated?
3. Attach your graph showing the results of the experiment and explain the figure. What should the reader take away from your experiment based on the graph?
4. Present your t-test statistic results:
a. What was the test statistic value for your experiment?
b. what is the probability that the differences observed between Groups l &2are due to chance alone?
c. Should the null hypothesis be rejected based on the t-test statistical results? Why did you make this conclusion?
d. What other experiments could be carried out to further test your hypothesis?
5. what improvements would you make to the experiment next time ran it?
Explanation / Answer
2 a: Independent Variables: The variables that stands alone do not change or controlled in a scientific manner by other variables are called independent variables. The best example of this is the age of the individual, which doesn’t have any effect of food, drinks and social factors.
Dependent Variables: The variables that can be affected by other variables is called independent variables. The effect of independent variable can be observed in dependent variable. The best example is effect of age on the physical efficiency of the individual.
2. b: Controlled variables are the variables that remain constant, as the researcher observe them as carefully as the dependent variables. The best example is temperature maintenance at 37 0C while culturing the E Coli Cells.
2. c: The experiment can be replicated by performing the same set of experiments at same optimized working conditions of that experiment. It could lead to the error free results with more specificity.
