According to the Scientific Method, in order to make a controlled experiment you NEED to have an hypothesis.
A controlled experiment consists of a test done by a scientist in which only one or a few variables are changed while the others remain constant in order to prove or disprove a hypothesis. This hypothesis is key to said experiment because it provides the starting point from which the professional can begin the procedure, as it helps focus on the subject that one is trying to get results from. Without a clear hypothesis, the outcome of the experimentation will not be valid nor specific.

If you are finding your clients through some of the established freelance markets like Upwork, you will notice that more designers have an hourly rate quote. Some designers charge as little as fifteen dollars an hour and others charge hundreds. The average is around USD forty-five dollars an hour for graphic designers.
A common approach to figuring out an hourly rate is to divide the salary you want by the number of hours worked each year: 40 hours/week × 52 weeks/year = 2,080 hours. $100,000 desired salary ÷ 2,080 hours = roughly $50 per hour.
Hope this helps you. Do mark me as brainliest.
