What is the independent and dependent event for pulling two marbles out of a bag?
The first marble is the independent event because its probability is only based on the sample space of the bag. The second marble is the dependent event because its probability is based on the sample space of the bag which has now been changed by the first marble.
What is not dependent on the size of a sample?
In general the mean of a truly random sample is not dependent on the size of a sample. By inference, then, so is the variance and the standard deviation.
What is independent probability?
An independent probability is a probability that is not based on any other event.An example of an independent probability is a coin toss. Each toss is independent, i.e. not related to, any prior coin toss.An example of a dependent probability is the probability of drawing a second Ace from a deck of cards. The probability of the second Ace is dependent on whether or not a first Ace was drawn or not. (You can generalize this to any two cards because the sample space for the first card is 52, while the sample space for the second card is 51.)
When are two random samples dependent?
Two random samples are dependent if each data value in one sample can be paired with a corresponding data value in the other sample.
What is dependent sample?
Data gathering in two different samples such that there is matching of the first sample data drawn and a corresponding data value in the second sample.

What is independent varible and a dependent variable?
An Independent Variable is the factor that is directly controlled or change. OR the part that you change.A Dependent Variable is the part measured or what you are looking for in the experiment.A constant is what never changes.A Sample Size is the # of subjects tested or observed.You're WELCOME!!!I literally JUST learned this in school today!

What is the definition of dependent sample?
two samples are independent if they are drawn from two different populations, and/ or the samples have no effect on each other. eg: We want to estimate the difference between the mean salaries of all male and all female executives. We draw one sample from the population of male executives and another from the population of female executives. These two samples are independent because they come from different populations and the samples have no effect on each other Rate This Answer
Is testing a group of 10 volunteers' blood pressure before and after exercise an example of an independent or dependent sample?
What you have written is the test...an independent variable may be something like the type/length of exercise, the dependant variable in this case is the blood pressure.
When are two samples dependent?
Two random samples are dependent if each data value in one sample can be paired with a corresponding data value in the other sample.
How many variables should there be in a good experiment?
There should be one dependent variables. Depending on the type of research you are doing, the amount of independent variables will change. If you are doing research on a large scale, you will use more independent variables. If it's on a small scale, you will use very little. If you are not able to run your regression it means your sample size is too small or you have too many independent variables.
When are two random samples dependent?
Two random samples are dependent if each data value in one sample can be paired with a corresponding data value in the other sample.
What type of t tests should be used for determining the difference in students computer anxiety based on whether or not they own computers?
independent sample t test
Difference between random sample and convenience sample?
random sample is a big sample and convenience sample is small sample
What is the difference between a sample and sampling?
sample is a noun and sampling is TO sample(verb)
