<span>The independent variable is the variable that does not change despite inputs. In this experiment, the independent variable is the color of mashed potatoes. The control group is what the experimental group is measured against to determine how much change there is. Plain potatoes is the control group. Number of samples is how many different opinions are taken into account. In this instance, the number of samples is equal to the number of students, or 100. There are no repeated trials. She only did the experiment one time.
The hypothesis is what the experimenter believes will happen. Gloria did not state the hypothesis for the experiment. She could have said, "I believe that students will choose colored mash potatoes than plain."
This experiment can be improved by repeating the experiment at more schools. Also, it can be improved by increasing the number of students tested.</span>
The flu is a very dangerous disease that is thankfully not anymore in circulation. When people working in government jobs are affected by this disease it delays the time they come to work and therefore the country's business goes down.
Also a large amount of money is spent by the government to cure this disease and the government has to focus on the eradication of these diseases and waste time.
When infected people use some resources and many citizens use the same resource then a large number of people could get affected due to this and therefore the country's economy is reduced with the resources.
Hope it helps you!
