Question

James investigates which type of material has more frictional force on a ball. He chooses concrete, carpet, wood flooring, and grass as his different materials. He describes the texture of each of these materials with words such as hard, soft, rough, and smooth. Before he rolls the ball on the material, the ball rolls down a ramp. This is done to make sure that the ball rolls with the same amount of force. What type of data is quantitative? describing the texture of the floor material measuring how far the ball travels on each material both of these choices neither of these choices

Answer 1

Answer:

it's experimental

Explanation:

James investigates which type of material has more frictional force on a ball. He chooses concrete, carpet, wood flooring, and grass as his different materials. He describes the texture of each of these materials with words such as hard, soft, rough, and smooth. Before he rolls the ball on the material, the ball rolls down a ramp. This is done to make sure that the ball rolls with the same amount of force.

What type of experiment is this?

Answer 2

Measuring how far the ball travels on each material is the quantitative data.

• Quantitative data is information that is expressed as counts or numbers, each of which has a specific numerical value. Data is any quantifiable information that may be used by academics for statistical analysis and mathematical computations so that they can derive practical conclusions.
• Quantitative information provides answers to inquiries like "How many?," "How often?," and "How much?" Mathematical methods can be used to easily verify and assess this data.
• For instance, there are numbers that correlate to different parameters. For instance, asking "How much did that laptop cost?" will gather quantitative information. Most measurement parameters have values attached to them, such as pounds or kilogrammes for weight, dollars for cost, etc.
• Here, the measure of distance travelled by ball can be answered in terms of quantity and number and the question of how much can be answered, so it is a quantitative data.

Hence correct answer is measuring how far the ball travels on each material.
