What is research design that has multiple independent and dependent variables?
Factorial designs
What allows researchers to rule out differences among participants as the cause of differences in the dependent variable?
Researchers can rule out differences among participants as the cause of differences in the dependent variable by employing random assignment in experimental designs. This process ensures that each participant has an equal chance of being placed in any group, thereby controlling for individual differences. Additionally, using control groups and blinding techniques helps mitigate biases and isolate the effect of the independent variable on the dependent variable. Consequently, any observed differences can be attributed more confidently to the experimental manipulation rather than participant characteristics.
When to use analysis of variance?
Analysis of variance (ANOVA) is used when comparing the means of three or more groups to determine if at least one group mean is statistically different from the others. It is appropriate when the data meets certain assumptions, such as normality and homogeneity of variances. ANOVA helps in identifying the effect of one or more categorical independent variables on a continuous dependent variable. It's commonly used in experimental designs and observational studies to evaluate group differences.
What do you learn for shapes and designs?
shapes and designs are all over the world you can be riding in the car and see a rectangle.there are many shapes and designs you see and guess what?they all come form nature
Mathematical designs patterns using arithmetic progression?
what do you mean by mathematical designs using arithmetic progression
A chemist hypothesizes that mercury oxide will undergo a decomposition reaction if it reaches a certain temperature When the chemist designs his experiment what should be the only independen?
The only independent variable should be the temperature at which the mercury oxide is heated. This variable will be manipulated by the chemist to determine its effect on the decomposition of mercury oxide.
When the biologist designs her experiment what should be the manipulated variable of the experiment?
temperature
Why do you think it is important that the experiment that the person designs only answer the question that they are asking?
I think it is important that the experiment that the person designs only answers the question they are asking because they might do something wrong and get the wrong idea.

After the scientist makes a hypothesis they perform a to collect data?
the answer is the scientist designs a scientific inquiry
What is research design that has multiple independent and dependent variables?
Factorial designs
Which part of an investigation is only found in an experimental investigation?
The part of an investigation that is only found in an experimental investigation is the manipulation of an independent variable. In experimental investigations, researchers deliberately change the independent variable to observe the effect on the dependent variable. This manipulation allows for the establishment of cause-and-effect relationships, which is a key component of experimental design. Control over the independent variable is a defining feature of experimental investigations that sets them apart from other types of research designs.
What is a research method that allows you to determine cause and effect?
An experimental research method allows you to determine cause and effect by manipulating an independent variable to observe its effect on a dependent variable while controlling for potential confounding variables. Random assignment of participants to different conditions is a key feature of experimental designs.
What are the three basic research designs?
Three basic research designs are experimental, correlational, and quasi-experimental.Experimental designs have random assignment to conditions. Correlational designs define the relationship between two measured values. Quasi-experimental designs have participants grouped on a variable that isn't manipulated.
A scientist who performs an experiment has no idea what the outcome of the experiment is going to be true or false?
True. In an experiment, a scientist formulates a hypothesis, designs the experiment, collects data, and then analyzes the results to draw conclusions. The outcome of the experiment is not known beforehand, and it is the results of the experiment that will either support or refute the hypothesis.
How many variables can be tested at a time?
An experiment should test only one variable (the independent variable) at a time. If you are testing more than one variable at a time, you have no idea which variable is causing which effect.
