Question

A student conducts an experiment to determine how the temperature of water affects the time for sugar to dissolve. In each trial, the
student uses a different amount of sugar and a different temperature of water.
What is wrong with this experimental design?
O The student did not change enough variables.
The student does not have a dependent variable.
The student changed too many variables.
The student needs to perform more trials.

Answer 1

Answer:

The answer is C: The student changed too many variables.

Explanation:

Answer 2

The error in the given experimental design would be:

C). The student changed too many variables.

• "Experimental Design" is characterized as the 'pattern in which participants are segregated among various groups for observation.'
• In the given experiment, the flaw that exists is that 'there are too many alterations in the variables' which will lead to not producing effective and desired outcomes.
• An experiment is usually observed to see the impact of change in the independent variable on the dependent variable. However, the alteration in the variables so much would impact the viability of the experiment and its product too.

Hence, option C is the correct answer.
