Statistics

I'm guessing you mean what are the types of surveys in general.

If so, then I can think of 4 types of surveys off the top of my head.

1. Online Surveys
2. Paid Surveys
3. Telephonic surveys
4. One-to-one interviews

There are also 3 types of surveys based on the frequency of deployment.

• Cross-sectional studies - These type of surveys offers a researcher a quick summary of what respondents think at that given time. These surveys are short and ready to answer and can measure opinion in one particular situation.

• Longitudinal surveys - Longitudinal surveys are those surveys that help researchers to make an observation and collect data over an extended period.

• Retrospective survey - A retrospective survey is a type of study in which respondents answer questions to report on events from the past. By deploying this kind of survey, researchers can gather data based on past experiences and beliefs of people.

I can tell you about this one Online Paid Survey site in particular, it’s called Zippy Opinion.

The survey invitations from this panel are super easy to complete and the time taken to complete a survey will not exceed 20 minutes.

This website pays more points for surveys and provides far more survey invitations to their panel members when compared to its counterparts.

This site runs loads of innovation contests on all its social channels and community pages wherein members can earn rewards worth USD $680(INR 5000) approx.

This awesome site also creates opportunities for the following:

• Voting Polls,
• Referring Friends &
• Participating in Social Media Community Discussions.

The Minimum Threshold to redeem points is 500 Points equivalent to UDS $6.

Panel members can redeem their points as Online gift vouchers

Just sign up to them and that's it.

There doesn't exist such a thing.

What does exist are standardized variables, which are variables with mean = 0 and standard deviation = 1

The answer depends on what you are looking for: the full sequence of results, the number of heads (or tails) the number of runs, the lengths of runs, or whatever.

7 of them. Remember, that in a combination the order of the numbers does not matter.

No. Some distributions and some sets of observations can have more than one modes. In such cases there is no unique mode.

Direct variation.

The vast majority of all graphs do that.

In fitting a logistic regression, as in applying any statistic method, the required sample size depends on the level of dispersion in the population and the quality of the statistics that you are prepared to accept.

Usually there will be some information available somewhere (in the literature, say, or from colleagues) suggesting what level of variability to expect in data that is collected. This can be used to simulate some data sets and the logistic regression results that would arise from them. By varying the sizes of the data sets you can make a judgement. Once you have collected your first sample and fit the actual logistic regression to it you will have a much better idea how much data is actually required for useful estimates.

Yes, they do.

As of recent data, Chile has approximately 1.5 million pigs. The country's pig farming industry is significant, contributing to both domestic consumption and exports. The sector has grown in recent years, driven by increasing demand for pork products. For the most accurate and current figures, it's advisable to consult official agricultural statistics or reports.

If it could be 3333, then your answer would be four to the fourth power, which is 256.

Can prove that as: The first number has 4 possibilities, and the second has 4 possibilities, so if each of the possibilities in the first number has four possibilities for the second number, the number of possibilities of the two is 16, and that can continue if the third number as four possibilities, so you can have 64 combination of those three numbers, and of those 64 numbers each of them could have 4 different numbers after them, so you have 256 combinations.

If it could not repeat digits it would be 4x3x2x1 which is 24.

can prove that as:

There are just two ways to get the value of 11 when dice are thrown. one would be a 5 and 6 and the other is a 6 and 5.

So they know not to make the same mistake again

it is an unusual variable called the protocathletica variable.

When data are nominal.

The probability of getting a red card out of a standard 52 card deck is 26 in 52, or 0.5. The probability of getting a second red card is 25 in 51, or 0.490, because one red card is missing, and the deck is short by one card. The probability of getting a black card next is 26 in 50, or 0.52, because the deck is short by two cards, but all the black cards are there. Multiply these probabilities together, and you get about 0.127, or about 1 in 8, so the probability of getting 2 red cards and then a black card in a random 52 card deck is about 1 in 8.

Using a decimal point, it would be .27 (normally written as 0.27).

This is somewhat smaller than 2/7 (which is about 0.286).

Why not -27 which is -128?

The answer depends on the purpose. The interquartile range and the median absolute deviation are both measures of spread. The IQR is quick and easy to find whereas the MAD is not.
