Biology Laboratory Research Paper I. The Scientific Method Scientists see the world from a different perspective. Scientists observe the environment and the surroundings and ask questions. Once questions are formulated the next step for a scientist is to try and come up with answers. This method of inquiry and analysis is called the scientific method. As previously mentioned the scientific method starts by asking questions and then trying to find answers. "Scientists use the scientific method

costs at the original budgeted activity level. True False 3. The overhead spending variance and the overhead efficiency variance are useful only if variable overhead really should be proportional to the activity measure that is being used in the flexible budget. True False 4. The variable overhead efficiency variance reflects how efficiently variable overhead resources were used. True False 5. A reason for keeping a constant denominator activity level is to maintain stability in the amount of

Three examples of a variable cost are a 12% increase in the production of dresses‚ which will cause a 12% increase in variable costs. A 10% increase in clothes will cause an 10% increase in variable costs. A 30% increase in labor hours will cause a 30% increase in variable costs. Three examples of a fixed cost are a 12% increase in airline costs but the fixed costs remain unchanged. A 50% increase
