Types of sampling techniques?
It is a sampling method in which units are selected based on easy access/availability. The disadvantage of convenience sampling is that the units that are easiest to obtain may not be representative of the population. For example products on top of a box of parts may be a different quality from those at the bottom, people who are at home when the market researcher calls may not be representative of the entire population. It is also called as Accidental Sampling.
What is sample and population relationship?
The sample is a subset of the population. For example, the population may be all the people at your school. A sample might be 5 people from each class. There are different types of sampling methods. The most commonly used is a simple random sample. When your obtain data from the entire population this is called a census.
What units obtain by combinding Sl units are called what?
Derived units
What are the two numbers you divide together called?
You divide the dividend by the divisor to obtain the quotient.
What are numbers you multiply together called?
The multiplicand is multiplied by the multiplier to obtain the product. They are both also known as factors.
Is it sampling time and sampling interval same?
Nope. Sampling time - is the amount of time it takes to obtain the sample. Sampling interval - is the period of time between samples. For example - it may take 10 seconds to obtain a sample. Obtaining a sample once a day is a sampling interval of 24 hours.

What is instrument flange?
Instrument flanges, (sometimes called Bleed Rings or Sampling flanges), allow a means to measure pressure or obtain fluid samples from a pressurized flange connected line. The instrument flange provides a means of having threaded ports in the line without drilling and tapping the principle equipment in the line (The operator can replace the instrument flange if the threaded ports should become damaged or begin to leak). Instrument flanges commonly have 2, 3, or 4 ports. The two common forms of instrument flanges, the drilled through type, and the double studded type, function interchangeability.
What is A process where a long thin tube is used to withdraw fetal cells from the fetal side of the placenta is?
The process you are referring to is called chorionic villus sampling (CVS). It involves using a long thin tube to obtain a small sample of cells from the chorionic villi on the fetal side of the placenta for genetic testing.

What is used to measure blood?
The instrument used to obtain blood pressure is a sphygmomanometer.
Why do we need sampling in research?
Sampling is essential in research to obtain representative data within a manageable time and cost. By selecting a subset of the population, researchers can draw conclusions about the larger group. It helps ensure that the findings are generalizable and applicable beyond the sample studied.
Does a barometer measure blood pressure?
The instrument used to obtain blood pressure is a sphygmomanometer.
What is used to obtain an endocervical tissue specimen?
