At 30,065 miles driven, the cost-of-driving calculator estimates the cost of driving a car as $1.39 per mile. To calculate the cost of driving a Ruckus we assume the price of a brand-new Ruckus is $2149, determine the cost of the gas it would cost to drive 30,000 miles, and then tack on the $96 insurance premium.
1 Testing measures the level of skill or knowledge that has been reached. 2  Evaluation is the process of making judgments based on criteria and evidence. 3  Assessment is the process of documenting knowledge, skills, attitudes and beliefs, usually in measurable terms.
Validity is a measure of how well a test measures what it claims to measure. Psychological assessment is an important part of both experimental research and clinical treatment. One of the greatest concerns when creating a psychological test is whether or not it actually measures what we think it is measuring. For example, a test might be designed to measure a stable personality trait but instead measure transitory emotions generated by situational or environmental conditions.
