Why do polls have different outcomes?
Because they are based on samples and outcomes vary between different samples.
True or false Analytic epidemiologic studies focus on potential causal associations between exposures and outcomes?
True. Analytic epidemiologic studies are designed to investigate and identify potential causal associations between exposures and outcomes by comparing groups exposed to different factors. These studies aim to assess the strength of the relationship between exposures and outcomes to draw conclusions about causality.
When analysing data or entries it is necessary to determine their expected outcome before recording them True of false and why?
It is neither true nor false.It is important that you have a view about the expected outcomes so that you can test whether or not the assumptions for the model - independent, identically distributed errors - is valid or not. While these are based on the differences between the expected and observed outcomes, it is not necessary to determine the expected outcomes beforehand. Determining their distribution is sufficient.
Probability can be defined as a ratio between the number of and number of possible outcomes?
yes it can be defined more commonly as a ratio between the number of and numbr of possible outcomes
Compare a manual record system and a computerized system?
compare between computerized recording and manul recording
4. What shows all of the possible outcomes of a genetic cross between male and female organisms?
A Punnett square shows all possible outcomes of a genetic cross between male and female organisms. It is a visual tool used to predict the probability of different genotypes and phenotypes in offspring based on the genotypes of the parents.
What is difference between pause recording and stop recording?
Pausing recording temporarily halts the recording process without ending it, allowing you to resume recording later from where you left off. Stopping recording ends the recording process entirely, creating a complete recording file that cannot be appended to.
What is the difference between pause recording and stop recording option in macros submenu in windows word 2010?
no difference,..
What is the difference between random variable and random variate?
Random variables is a function that can produce outcomes with different probability and random variates is the particular outcome of a random variable.
What is the difference between a digital cable dvr and a vcr?
A digital cable dvr is different from a vcr because one takes VHS tapes, and the other records tv shows digitally to a hard drive so you can watch them later.
A probability is a ratio of a fraction in between?
If the outcomes of the trials are equally likely, then (and only then) is it the number of favourable outcomes and the total number of trials.
If you flip 5 coins how many possible outcomes are there?
If each coin is a different color, then there are 32 possible outcomes. If you can't tell the difference between the coins, and you're just counting the number of heads and tails, then there are 6 possible outcomes: 5 heads 4 heads 3 heads 2 heads 1 heads all tails
