It is 20 multiple choice question survey that takes about 10 minutes. It is taken after the program, versus a baseline survey which is taken before the program. The endline survey measures how much has changed since the first time you took the baseline survey.
this is brief, but a census gathers data from the whole group/poulation, wheras a sample investigation on takes a small part of the group/poulation, a sample
A random sample is better than a census because it takes less time and costs less.
A survey is used more often than a census because a census requires everybody to respond, while a survey only needs a few people. This means a survey is advantageous for many reasons:It doesn't matter if not everyone responds, you can just survey more people.It is much cheaper to survey than hold a census.It is less effort to hold a survey than hold a census.It takes less time to hold a survey than hold a census.
A sample is a subcollection of members selected from a population. (Ref Triola, Elementary Statistics). A sample may be real or hypothetical. Real- Ten patients at the hospital were interviewed about the care they received. Hypothetical- Repeatedly drawing n independent, and identical values X1, X2... Xn from a normal distribution to form a random sample, the mean of this sample should conform to a normal distribution, if the sample size is greater than 30.
Biased- (Not random) Unbiased-(Random) Example: (ubbiased) Woman takes random people to take a survey.
Researchers define a "population" which consists of elements with defined characteristics. Example: All the matriculating students at Providence College. If the researcher studies the entire population as defined above, it is called a "census". If, on the other hand, the researcher takes a subset of the population, a sample, and studies it it will be a sample survey (or study in more general terms.)
The time it takes for half the sample to decay is called the half-life.The time it takes for half the sample to decay is called the half-life.The time it takes for half the sample to decay is called the half-life.The time it takes for half the sample to decay is called the half-life.

The time it takes to get results from a seismic survey can vary depending on the size and complexity of the survey. Generally, it can take anywhere from a few weeks to a few months to process and interpret the data collected during the survey.
The time it takes for half of a sample to decay is called the "half-life" of the corresponding material.
Response rate is the number of people who completed the a survey divided by the number contacted, very roughly. The term CASRO refers to the "Council of American Survey Research Organizations" who developed a much more complicated formula which takes into account non-eligible people/households in the main sample, among other things, to make the response rate more accurate.
There are some survey sites that are legitimate. Each survey takes about 15 minutes (they all follow the same format), and you get $3 per. The one downside is that you have to do some work to sign up.
Companies pay the survey site to find out what everyone likes. Then the the surveysite pays you to know what you like so they can get the money from the company.The company pays like $500 per survey, and that's how you and everyone else who takes the survey can get like a dollar from doing it. The survey site keeps the rest.
