PRF is based on population data as a whole,
SRF is based on Sample data
2.
We can draw only one PRF line from a given population.
But we can Draw one SRF for one sample from that population.
3. PRF may exist only in our conception and imagination.
4.
PRF curve or line is the locus of the conditional mean/ expectation of the independent variable Y for the fixed variable X in a sample data.
SRF shows the estimated relation between dependent variable Y and explanatory variable X in a sample.

What is the difference between random sampling and random assignment?
Random assignment: assigning participants to experimental and control conditions by chance Vs. Random sample: a sample that fairly represents a population because each member has an equal chance of being included You decide :-D
The table below shows some data for the function Vs which shows the volume V of a pyramid with a given side length s What is V5 - V2?

The equation below shows the rule for the function VS use it to find the number of cubic meters of cement needed to make a pyramid with four metered sides round your answer to the nearest hundredth?

Independent vs dependent varibles?
Independent variables are ones that are not impacted by outside forces or other factors. Dependent variables are the ones that are impacted by other elements and need other elements in order to function.
What is a math sample using debit cards vs credit cards?
A Debit card is just like writing a check. The money comes out of your checking account right away. A Credit card sends you a bill and then you pay it. No money leaves you until you pay the bill.

How do you figure out the starting point of a distance vs time graph when given the velocity vs time graph and a function?
To find the starting point of a distance vs time graph from a velocity vs time graph and a function, you would integrate the velocity function to find the displacement function. The starting point of the distance vs time graph corresponds to the initial displacement obtained from the displaced function.
What song did kid vs play the battle sample?
Joyous by Pleasure
What is the function of vs sensor?
bog off
What is the formula for void ratio?
Void ratio (e) is typically defined as the ratio of the volume of voids to the volume of solids in a soil sample. The formula for void ratio is e = Vv/Vs, where Vv is the volume of voids and Vs is the volume of solids in the soil sample.
What is The issue that discusses whether development is more a function of biology or more a function of the environment?
Nature vs nurture
What controversy discusses whether development is more a function of biology or more a function of the environment?
The name of this controversy is Nurture Vs Nature.
What type of population is found in Yukon?
The current population is 33,89, and 13% are of aboriginal, North American Indian, or Matis origin. The categories for other origins are confounding ('European' vs 'Western European' vs 'French' vs 'Scottish', etc.) and therefore a further breakdown is not realistic.
What is a sample of an investigatory project related to biology?
Investigate what kills ants. Example: Using spices vs. brand name poison to kill them.
What does unspecialised?
Unspecialised means no specialised function. For example ciliated cells vs nonciliated cells.
What does unspecialised mean?
Unspecialised means no specialised function. For example ciliated cells vs nonciliated cells.
What is the rate of change of velocity with distance?
acceleration/decceleration it is the second derivative of a displacement vs time function
