What are measures in quantitative research?
Measures exist to numerically represent degrees of attributes. Quantitative research is based on measurement and is conducted in a systematic, controlled manner. These measures enable researchers to perform statistical tests, analyze differences between groups, and determine the effectiveness of treatments.
What are examples of measuring tools?
5 Measurement Tools Every Workshop Needs
- Tape Measure. A well-worn tape measure signifies a builder who takes their work seriously.
- Speed Square. A speed square can be found on the hip of carpenters and DIYers everywhere.
- Protractor.
- Mechanical Carpenter’s Pencil.
- Laser Measure.
What are the 2 types of measuring cups?
There are two main types of measuring cups—dry measuring cups and liquid measuring cups—and it matters which one you use. Dry measuring cups are designed to measure dry ingredients like flour, nuts, and berries, while liquid measuring cups are designed to measure liquids like water, cooking oil, and yogurt.
What are the 7 basic units of measurement?
The seven SI base units, which are comprised of:
- Length – meter (m)
- Time – second (s)
- Amount of substance – mole (mole)
- Electric current – ampere (A)
- Temperature – kelvin (K)
- Luminous intensity – candela (cd)
- Mass – kilogram (kg)
What are the three basic units of measurement?
The three most common base units in the metric system are the meter, gram, and liter. The meter is a unit of length equal to 3.28 feet; the gram is a unit of mass equal to approximately 0.0022 pounds (about the mass of a paper clip); and the liter is a unit of volume equal to 1.05 quarts.
What is SI unit of weight?
The SI unit of weight is the same as that of force: the newton (N) – a derived unit which can also be expressed in SI base units as kg⋅m/s2 (kilograms times metres per second squared).
What is SI unit of electric resistance?
The SI derived unit of electric resistance is the ohm, which is defined as a volt per ampere. A statcoulomb is defined as ohms where c is the magnitude of the speed of light, and is energy-equivalent to the unit second per centimeter (). A preece is defined as ohms.
What is SI unit of inductance?
The henry (symbol: H) is the SI derived unit of electrical inductance.
What is the formula of resistance?
The resistance formula is as follows: Resistance = voltage drop across a resistor/ current flowing through a resistor. R = IV. R = resistance (Ohms, Ω) V = voltage difference which is between the two ends of a resistor (Volts, V)
What is the dimensional formula for electric resistance?
Therefore, resistance is dimensionally represented as M L2 T-3 I-2.
What is the dimension of electric field?
Or, E = [M1 L1 T-2] × [I1 T1]-1 = [M1 L1 T-3 I-1]. Therefore, the Electric Field is dimensionally represented as [M1 L1 I-1 T-3].

WHAT IS A in dimensional formula?
Hint – Dimension formula is the expression for the unit of a physical quantity in terms of the fundamental quantities. The fundamental quantities are mass (M), Length (L) and time (T). A dimensional formula is expressed in terms of power of M, L and T. These will specify the nature of the unit and not its magnitude.
What is the dimension of coefficient of viscosity?
Or, η = [M L T-2] × [L] × [L2]-1 × [L1 T-1]-1 = [M1 L-1 T-1]. Therefore, the Coefficient of Viscosity is dimensionally represented as [M1 L-1 T-1].
