When all the items in a population have an equal chance orocesss f being selected for a sample the process is called?
Random Sampling.
How can sampling error be reduced?
The best way to reduce sampling error is to use random sampling in the study. This means selecting the population to study through a random process. This will ensure that each member of the population under study has an equal chance of being selected.
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
What is the difference between stratified an random sampling?
In (Simple) random sampling, all of the units in the sample have the same chance of being included in the sample. Units are selected randomly from a population by some random method that gives equal probability to each element. In stratified random sampling, the entire population is divided into heterogeneous sub-popuation known as strata (sub-population with unequal variances) and a random sample is chosen from each of these stratum. The reason when to use which depends on the situation and need of the experimenter.
Why probablity sampling is better than non probablity sampling?
i think it give equal chance for all.
When every individual in a large population has a small but equal chance of being included in a survey researchers are using a procedure known as?
Random Sampling

When every member of a population has the chance of being selected based on the probability or frequency of its representation in that population you are using which type of sampling?
Systematic sampling
When every Member of a population has the chance of being selected based on probability what type of sampling is this?
Simple random sampling.
What type of sampling uses a fair representation of the population?
Simple random sampling gives you are fair representation of the population. Every member of the population has an equal chance of being chosen.
What is probability sampling and non probability sampling?
In probability sampling,every item in the population has a known chance of being selected as a member.In non-probability sampling, the probability that any item in the population will be selected for a sample cannot be determined.

What is the difference between probability sampling and simple random sampling?
Simple random sampling = A process of selecting subjects in such a way that each member of the population has an equal likelihood of being selected; you can throw all your subjects into a hat and draw them out one by one, or assign each member a number and choose every fifth number to be a participant.Probability sampling=A sampling procedure in which the probability that each element of the population will be included in the sample can be specified; you have a specific number of subjects and you know that they have a 50/50 chance of being chosen, or because of an anomaly, they may only have a 20/100 chance of being chosen for the experiment.*Your teacher is being tricky however, because there are 4 basic types of Probability sampling and simple random sampling is one of them. Also are stratified, systematic and cluster sampling. All four fall under the general title of Probability Sampling (P.S.)!! P.S. is kinda like the category and the 4 types are just different ways to do the sample, each has their own "little differences" in how the data is collected and assigned.
If fewer of individual from a population are chosen at random for an experiment group?
A it is lees likely that differences among them will destroy the test results B the chance of sampling error is unpredictable C the it is almost impossible that differences among them will destroy the test results D the chance OS sampling error is greater E the chance of sampling error is smaller

How probability sampling is used?
Probability sampling is used to select a sample from a population in such a way that every individual or element in the population has a known and non-zero chance of being selected. This method ensures that the sample is representative of the population, allowing for generalizations and statistical inferences to be made with greater validity and accuracy. Probability sampling techniques include simple random sampling, stratified sampling, cluster sampling, and systematic sampling.
