A sample that is treated exactly like the other experimental groups except that the variable is not applied to it?
A control group.
SUPPOSE WE study the CONTINUOUS VARIABLE: "REPAIR TIME of A machine, in MINUTES". where the POPULATION average IS 135MIN. A SAMPLE of 20 OBSERVATIONS of THAT VARIABLE IS TAKEN. IS possible for the SAMPLE MEAN TO BE EXACTLY EQUAL TO 135MIN?
Yes, it is possible for the sample mean to be exactly equal to 135 minutes. This is because the sample mean is calculated by dividing the sum of all the observations by the number of observations. Therefore, if the sum of all the observations is exactly equal to 2700 minutes (135 times 20), the sample mean would be 135 minutes. However, this is highly unlikely to happen.
What does to the nth degree mean?
It means to the ultimate level of whatever it is you're talking about. It comes from the use of "n" as a variable in mathematics, implying that although we don't know exactly what that ultimate level is, that is what has been reached.
What is the probability of exactly 3 girls out of three children?
There is no simple answer to the question because the children's genders are not independent events. They depend on the parents' ages and their genes.However, if you assume that they are independent events then, given that the probability of a girl is approx 0.48, the probability of three out of three being girls is 0.1127.
What is the purpose of central tendency measures?
It is a measure of the middle or central value of a variable of interest. There are different measures of central tendency and their purposes are not exactly the same. However, the basic principle is that the observed values of the variable are more likely to be near the central tendency value than far from them. Some central tendency values cannot ever be observed. A normal number cube, for example, has a mean value of 3.5 but you cannot possibly throw a 3.5!
A function is a rule that assigns each value of the independent variable to exactly value of the dependent variable?
false
A function is a rule that assigns each value of the variable to exactly one value of the dependent variable?
I found two answers for this question. A function is a rule that assigns to each value of one variable (called the independent variable) exactly one value of another variable (called the dependent variable.) A function is a rule that assigns to each input value a unique output value.
A is a rule that assigns each value of the independent variable to exactly one value of the dependent variable?
This will be a math function. Each choice is only going to have one answer in this kind of function.
Is dependent variable the variable that can't change?
Not exactly sure what you mean by "can't change." However, I if I do understand you correctly, the dependent variable CAN change. The dependent variable will change according to the independent variable's value and overall effect. For example, in an experiment involving water's effect on plants, the dependent variable may be the height of the plant or the glucose produced. Based on the amount of the independent variable (represented on the x axis of a data graph), the dependent variable will increase or decrease. In this case, both dependent values (glucose and height) would probably increase.
How do you test one independent variable and one dependent variable?
In an equation like y = mx + b, such as y = 3x + 2, x is the independent - YOU put in the x. y is the ANSWER you get, depending on what you used for x. To test, do exactly that - you choose what to do for your independent variable, and see what happens for the y. Works for both math and science. Change the independent variable, and compare how your dependent variables change depending on what changes you made to the independent.
What is an independent variable and dependent variable?
Question: What's a variable?Answer: A variable is an object, event, idea, feeling, time period, or any other type of category you are trying to measure. There are two types of variables-independent and dependent.Question: What's an independent variable?Answer: An independent variable is exactly what it sounds like. It is a variable that stands alone and isn't changed by the other variables you are trying to measure. For example, someone's age might be an independent variable. Other factors (such as what they eat, how much they go to school, how much television they watch) aren't going to change a person's age. In fact, when you are looking for some kind of relationship between variables you are trying to see if the independent variable causes some kind of change in the other variables, or dependent variables.Question: What's a dependent variable?Answer: Just like an independent variable, a dependent variable is exactly what it sounds like. It is something that depends on other factors. For example, a test score could be a dependent variable because it could change depending on several factors such as how much you studied, how much sleep you got the night before you took the test, or even how hungry you were when you took it. Usually when you are looking for a relationship between two things you are trying to find out what makes the dependent variable change the way it does.Many people have trouble remembering which is the independent variable and which is the dependent variable. An easy way to remember is to insert the names of the two variables you are using in this sentence in they way that makes the most sense. Then you can figure out which is the independent variable and which is the dependent variable:(Independent variable) causes a change in (Dependent Variable) and it isn't possible that (Dependent Variable) could cause a change in (Independent Variable).For example:(Time Spent Studying) causes a change in (Test Score) and it isn't possible that (Test Score) could cause a change in (Time Spent Studying).We see that "Time Spent Studying" must be the independent variable and "Test Score" must be the dependent variable because the sentence doesn't make sense the other way around.
Difference between dependant and independant variable?
dependent: factors of a experiment that scientist observe, and can be changed by the outcome of the independent variable independent: a factor of a experiment that changes because you change it on purpose
When can we say that a function is a relation?
When it doesn't fulfill the requirements of a function. A function must have EXACTLY ONE value of one of the variables (the "dependent variable") for every value of the other variable or variables (the "independent variable").

What is it called exactly what you are going to measure?
A dependent variable.
What isdependent variable?
The dependent variable in an experiment is the thing that changes due to the experimentor changing the independent variable. Basically, its what you measure and record. For example: you create an experiment that observes the effects of the amount of sunlight on plants. You give one plant more sunlight than the other, leaving everything else exactly the same. That is your independent variable. Say you measure the height of each plant every week. Since the height is DEPENDENT on the amount of sunlight each plant got, the height is your dependent variable.
How do scientist usually test for one variable?
To test a single variable, scientists will change only that one variable (called the independent variable) whilst keeping everything else that could possibly affect the results of the experiment exactly the same. The other variables that are affected by the independent variable changing (called dependent variables) are then measured, and a conclusion can be made.
