What is the factor will affect the result of the experiment?
1 Expert Answer Variables: These include variables you change to test a hypothesis, variables you measure to determine results and variables you hold constant to produce a valid experiment. The following are the basic types of variable that are relevant to experiments.
Why are measurements important in a lab?
When taking scientific measurements, it is important to be both accurate and precise. Accuracy represents how close a measurement comes to its true value. This is important because bad equipment, poor data processing or human error can lead to inaccurate results that are not very close to the truth.
Which of the following factors affect the accuracy of an instrument?
Environment Temperature press humidity. Clean surrounding and minimum vibration. Adequate illumination. Temperature equalization between standard w/p and instrument.
What is the relationship between circumference and diameter?
Circles are all similar, and “the circumference divided by the diameter” produces the same value regardless of their radius. This value is the ratio of the circumference of a circle to its diameter and is called π (Pi).
Which one of the following factors affect the accuracy of instrument?
Which one of the following factors affects the accuracy of parts? Explanation: Unsteady and uneven abrasive flow affects the dimensional accuracy. 3.
What factors affect accuracy and precision?
-Stability with time. -Elastic properties. -Geometric compatibility. -Surface finish, waviness, scratch, surface defects etc., -Hidden geometry.
What is the importance of measuring accurately?
Accurate measurements are important because precise amounts are required for reactions to take place, for a recipe to turn out and to keep correct records of a measurement. When measurements are not accurate, this provides incorrect data that can lead to wrong or even dangerous conclusions or results.
Why is equipment management important in a laboratory?
Equipment management is one of the essential elements of a quality management system. Proper management of the equipment in the laboratory is necessary to ensure accurate, reliable, and timely testing.
What are the dangers of working in a laboratory?
The most common equipment-related hazards in laboratories come from devices powered by electricity devices for work with compressed gases, and devices for high or low pressures and temperatures. Other physical hazards include electromagnetic radiation from lasers and radio-frequency generating devices.
What are the factors that can affect the laboratory tests?
When interpreting laboratory test results, a common sign of the effect of sex, age is observed. Also, the other variables are ALP or serum alkaline phosphate, which is asking for liver function. The upper limit of reference can increase reportedly during puberty as it is the time of maximum remodeling of bones.
How is the room temperature in a laboratory affected?
Most laboratories’ room temperatures fluctuate between 20 and 25 °C [13]. Room temperature and ambient temperatures are directly affected by the heating and cooling system. Due to air flow patterns, hot and cold spots occur in the laboratory [13].
