sample size is the specific size of a thing like the how long or wide. while sample unit is the whole thing not referring to specific number size.
unit sample is defined by $(n)= 1 at n=0; = 0 otherwise; Used for to decompose the arbitrary signal x(n) into summation of weighted and shifted unit samples as follows x(n)=( summation of limit k=- infinite to + infinite) x(k)$(n-k)
Unit sample response refers to the output of a system when it is subjected to a unit impulse input, typically represented as a delta function. It characterizes the system's behavior and is crucial in understanding its dynamics, as it effectively captures how the system responds to a brief, instantaneous input. This response is fundamental in linear time-invariant (LTI) systems and is used to analyze and design systems in fields like control theory and signal processing. By convolution of the unit sample response with any input signal, one can determine the system's output for that input.
A population survey, better known as a census, entails the collection of each unit in the population. In sample survey information is collected from a subset of the population. The subset, or sample, needs to be selected carefully so that it is representative of the whole population and, if that requirement is met, statistics based on the sample are good estimators for the corresponding population parameters.

To find the number of moles in a sample, divide the sample's mass by the substance's atomic mass unit (amu). For a substance with an amu of 12, the number of moles in the sample can be calculated by dividing the sample's mass by 12.
Its density.
A liquid dilution system which dilutes a sample to be analyzed with a carrier to supply a diluted sample-containing liquid to an analytical measurement apparatus of flow type. The inventive dilution system features simplicity and versatility as compared to conventional automatic apparatus with robot concept, and the present system comprises: a first carrier pump for feeding a first carrier; a sample injection unit for injecting the sample into the first carrier; a main passage for flowing a liquid from the sample injection unit to a detector unit of an analytical measurement apparatus; a branching device located downstream of the sample injection unit for forming a branched passage to remove a liquid mass partially from the main passage; a confluence unit located downstream of the branching unit for confluencing a second carrier; and a second carrier pump for feeding the second carrier to the confluence unit. Dilution and mixing of the sample with a carrier is done twice, once at the sample injection and then again at confluence.
Unit.
The density of a mineral sample is a measure of its mass per unit volume. It can be calculated by dividing the mass of the sample by its volume. The density of a mineral sample is a characteristic property that can help in identifying the mineral.
you use centimeters to measure blood.
The key feature is that each sample of the given size has the same probability of being selected as the sample. Equivalently, each unit in the population has the same probability of being included in the sample.

The population consists of every possible unit where a sample is a subset of the population. Note that population and sample need not refer to persons. For example, if studying biodiversity, the population could consist of plots of land.
In optical density measurements, D typically stands for "Absorbance" and is commonly used as a unit of measurement to quantify the amount of light absorbed by a sample. The higher the D value, the more light is absorbed by the sample.
