What is a stratified random sample?
Stratified random sampling is a sampling scheme which is used when the population comprises a number of strata, or subsets, which are similar within the strata but differ from one stratum to another. One example is school children stratified according to classes, or salaries stratified by departments.A simple random sample may not have enough representatives from each stratum and the solution is to use stratified random sampling. Under this scheme, the overall sampling proportion (sample size/population size) is determined and a sample is drawn from each stratum which represents the same proportion.
When is it appropriate to use stratified random sampling?
it can be used when members of the population are heterogenous
Which is an effective use of stratified sampling?
Analyzing 20% of the items that are under $25,000
Example of multistage sampling?
the combinitoin of any random samples is called multistage samplinag. it is the expensive form of cluster samling. when each elements in cluster are expensive then we use multistage sampling.
Why you use sloven's formula?
it's a random sampling technique formula to estimate sampling sizen=N/1+N(e)2n- sampling sizeN-total populatione-level of confidence
What is solution formula?
A solution formula provides a clear and concise way to represent the components and proportions of a solution. It typically lists the solvent (the substance in which the solute dissolves) and the solute (the substance that is being dissolved) along with their respective amounts. The formula helps to ensure accuracy and consistency when preparing solutions for experiments or practical use.
What is sampling up?
Sampling up an image is the same with enlarging it. You can use up sampling to fit an image to a larger surface.
How can one determine the dilution concentration of a solution?
To determine the dilution concentration of a solution, you can use the formula: C1V1 C2V2. This formula relates the initial concentration (C1) and volume (V1) of the original solution to the final concentration (C2) and volume (V2) of the diluted solution. By rearranging the formula and plugging in the known values, you can calculate the dilution concentration of the solution.
How can one determine the molarity of a diluted solution?
To determine the molarity of a diluted solution, you can use the formula: M1V1 M2V2. This formula relates the initial molarity (M1) and volume (V1) of the concentrated solution to the final molarity (M2) and volume (V2) of the diluted solution. By rearranging the formula and plugging in the known values, you can calculate the molarity of the diluted solution.
How do you account for the dilution factor when calculating the concentration of a solution?
To account for the dilution factor when calculating the concentration of a solution, you can use the formula: C1V1 C2V2. This formula helps you determine the final concentration (C2) after diluting a solution by a certain factor.
Why its is necessary to use sampling in statistical investigation?
Sampling gives good insight of the choosen sample
What kind of sampling do researchers use to estimate population parameters on individual data A.population sampling b.nonprobability sampling c.ad hoc sampling d.cultural sampling e.probability sam.?
The answer depends on the cost of the various options and the required accuracy of the reusults.
How can one determine the solute potential of a solution?
To determine the solute potential of a solution, you can use the formula: s -iCRT. This formula takes into account the number of particles in the solution (i), the gas constant (R), the temperature in Kelvin (T), and the concentration of the solution (C). By plugging in these values, you can calculate the solute potential of the solution.
How do you calculate the concentration of a solution using Beer's Law?
To calculate the concentration of a solution using Beer's Law, you can use the formula A lc, where A is the absorbance of the solution, is the molar absorptivity of the substance, l is the path length of the cuvette, and c is the concentration of the solution. By rearranging the formula, you can solve for the concentration of the solution, c A / (l).
How can one determine the volume using molarity and moles in a solution?
To determine the volume of a solution using molarity and moles, you can use the formula: volume (in liters) moles / molarity. This formula helps calculate the volume of a solution based on the amount of solute (moles) and the concentration of the solution (molarity).
