What else can I help you with?
What is the variable in a science experiment?
The element of the experiment that the scientist changes in order to observe different outcomes.
What the deference between variable and variate?
A random variate is a particular outcome of a random variable: the random variates which are other outcomes of the same random variable would have different values.
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 a factor that affects the outcomes of an experiment?
Variable
A sweater comes in 3 sizes and 6 colors what is the number of possible outcomes?
The number of outcomes depends on what the experiment is! If the variable of interest is the size, there are just three outcomes. If the variable of interest is price, then there is not enough information to determine the possible outcomes.
In a spreadsheet Can a variable be changed?
Yes, in a spreadsheet, a variable can be changed by editing the cell that contains it. This can be done manually by typing a new value or by using formulas to update the variable based on other cell values. Additionally, if the variable is part of a formula, changing any referenced cells will automatically update the result.
What is the independent variable in an experiment designed to investigate the effects of alcohol consumption on memory?
In this experiment, the independent variable would be the amount of alcohol consumed by the participants. Different amounts of alcohol would be administered to different groups to observe the effect on memory.
An experiment is designed to compare the differences in health outcomes In the hospital by therapy cats and people who are not . Which of these is the independent variable?
The independent variable in this experiment is the presence of therapy cats in the hospital. The independent variable is what is being manipulated or controlled by the researchers to observe its effect on the dependent variable, which in this case would be the health outcomes of the patients.
What is control in an experiment?
Controlled experiments are used to investigate the effect of a variable on a particular system.
What are some characteristics of probability?
It is a real number. It cannot be negative. The sum of the probabilities of all possible outcomes of a discrete variable is 1. Similarly, the integral of the probabilities over the whole range of possible outcomes of a continuous variable is 1.
What variable did you change in your experiment?
I changed the independent variable in my experiment, which is the variable that is intentionally manipulated or changed to observe its effect on the dependent variable. This change allows for me to test the relationship between the variables and analyze the outcomes of the experiment.
If the outcomes of a random variable follow a Poisson distribution then their?
means equal the standard deviation
