What is the meaning of hypothesis in statistics?
A hypothesis is the first step in running a statistical test (t-test, chi-square test, etc.) A NULL HYPOTHESIS is the probability that what you are testing does NOT occur. An ALTERNATIVE HYPOTHESIS is the probability that what you are testing DOES occur.
How do you calculate the probability of observing a sample proportion of .32 or more?
You need a null hypothesis first. You then calculate the probability of the observation under the conditions specified by the null hypothesis.
What is a variable interval schedule?
Variable-interval schedule (VI) is a reinforcement schedule in which reinforcement is provided for the first response that occurs after a variable amount of time from the last reinforcer or the start of the trial interval.
When constructing a data table where should the values of the independent variable be placed?
in the first column on the left
How do you determine which variable goes on the x axis on a line graph?
You can determine which variable that goes on the x axis on a line graph by checking the number that comes first in a set of pair or from table, e.g [2,4]. 2 will be on the x axis because it is the first number in the pair
The four main parts of an experiment?
First and foremost you must specify the hypothesis you are testing by the experiment. So you will have a testable null and alternate hypothesis. Next you will detail the resources and procedures used to generate the data needed by the tests specified by the hypothesis. Then using the described resources and procedures you will generate and record the data specified by the first two components. Next you will perform the analytic tests on those data, and record those results relative to the specifications made by your hypotheses. Following that you will write a summary of your results test and conclude whether your null hypothesis was shown to be not false based on you experimental results. Finally, you will write recommendations for further action and/or experiments based on your own experiment.
Why is the output value called the dependent variable?
because it can change according to the independent variable. this dependent variable depends on the independent variable for its output. the independent variable is not affected by the dependent variable because the independent variable if found out first.
What comes first independent or dependent variable?
Independent variable
What variable goes first in the title of a line graph for science?
The dependent variable goes first.
What is the difference between independent variables and dependent variables?
The independent variable is the variable being manipulated in the experiment in order to show the effect on the dependent variable. It is also called the experimental variable.The dependent variable is the variable being observed in the experiment. Changes in the dependent variable as a result of changes in the independent variable are observed, which is the purpose of the experiment. Dependent variable is also called the response variable.
How can an independent variable be identified?
It is the quantity that is controlled. The dependent variable is the one that changes accordingly: it depends on the first one.
How do you form a differential equation?
You write an equation that involves an independent variable (for example "x"), a dependent variable (for example "y"), and the first derivative, or higher-level derivatives, of the dependent variable (for example, dy/dx).
Manipulated variable is also known as?
The manipulated variable is your independent variable. This gets plotted along the x-axis on a graph, and your dependent variable gets plotted along the y axis. Example- think of a velocity-time graph (physics), or a dose-response graph (pharmacology). The variable you are able to control (like time or dose) is your manipulated variable, and the variable whose value is contingent on how you manipulate the first is your dependent variable (drug response etc.)
Compare dependent variable and independent variables?
well a independent variable is usually the one that is manipulated and is the x axis while the dependent is the one that depends on the independent and is the responding variable and the x-axis!A little saying i use is dry mix/dependent,responding,y axis/manipulated variable,independent,x axis.tale the first letter of all of that and you get dry mix.
What is a dependent variable in science mean?
Typically in an experiment there will be one or more conditions that are varied while one or more other conditions are monitored and measured. The first type of condition is considered the independent variable, while the second type, the type you measure while varying the first, is called the dependent variable. For example, you might vary the weight of the mass at the bottom a pendulum while measuring the period of the pendulum when it is swung. The weight of the mass is the independent variable while the period is the dependent variable in this case.
What variable precedes the other when thinking of independent and dependent variables?
The independent variable is named first. In the Cartesian plane, this means you write (X, Y).
What is a dependent variable mean in science fair?
Typically in an experiment there will be one or more conditions that are varied while one or more other conditions are monitored and measured. The first type of condition is considered the independent variable, while the second type, the type you measure while varying the first, is called the dependent variable. For example, you might vary the weight of the mass at the bottom a pendulum while measuring the period of the pendulum when it is swung. The weight of the mass is the independent variable while the period is the dependent variable in this case.
