Front

What is qualitative data?

Back

Qualitative data refers to descriptive information that cannot be measured numerically. It often includes characteristics, qualities, or attributes, such as color, texture, or taste.

Front

What is quantitative data?

Back

Quantitative data refers to numerical information that can be measured and expressed mathematically. It includes counts, measurements, and values, such as height, weight, or temperature.

Front

What is the formula for calculating density?

Back

Density = Mass / Volume. It is expressed in units such as g/cm³ or kg/m³.

Front

How do you convert centimeters to millimeters?

Back

To convert centimeters to millimeters, multiply the number of centimeters by 10. (1 cm = 10 mm)

Front

What is the significance of significant figures in measurements?

Back

Significant figures indicate the precision of a measurement. They help convey how accurate a measurement is and how many digits are reliable.

Front

What is the result of 20.2 cm ÷ 7.41 s?

Back

2.73 (rounded to two decimal places).

Front

If an object has a density of 3.6 g/cm³ and weighs 15.0 g, what is its volume?

Back

Volume = Mass / Density = 15.0 g / 3.6 g/cm³ = 4.2 cm³.

Front

Convert 4.80 centigrams to milligrams.

Back

4.80 cg = 48 mg (since 1 cg = 10 mg).

Front

Which unit is NOT acceptable for density?

Back

ng/m is NOT an acceptable unit for density.

Front

What is the relationship between mass, volume, and density?

Back

Mass is directly proportional to density and volume. As density increases, for a given volume, mass increases.
