WHAT IS THE Difference between A t test and chi square?
t test is used when- a) variables are studied b)the size of sample is a small one.(n<30) chi square test is studied when a) attributes are studied
What is the length width and height of a sea anemone?
The length, width, and height of a sea anemone varies greatly. These variables differ based on age and on the species of sea anemone studied.
Why are graphs useful in science?
graphs give a trend of variables and the trend can be studied using the the extent they usually portray and the graphs are not emperical methods they give interpolated relationships hence a reduced uncertainities
What is the differecnce between independent variables and dependent variables?
Every time the independent variables change, the dependent variables change.Dependent variables cannot change if the independent variables didn't change.
What are controlled independent and dependent variables?
control variables: the things that are not changing.Independent variables: the things that you change.Dependent variables: the things that are changed due to the independent variable
What are variables that are not being studied called?
Independent Variables.
How many variables should be studied in an ideal scientific experiment?
ONE :)

What are variables in a qualitative study?
In qualitative studies, variables are the concepts or factors that are being studied. These variables are often abstract and subjective in nature, such as beliefs, experiences, or feelings. Researchers aim to understand the relationship or connections between these variables through in-depth analysis and interpretation.
Why are variables isolated?
Variables are isolated in order to prevent interference or contamination from other factors. By isolating variables, researchers can accurately determine the effect of the specific variable being studied. This helps ensure the validity and reliability of the results obtained from an experiment.
What Confounding variables are there on a questionnaire?
Confounding variables on a questionnaire refer to factors that may influence the relationship between the variables being studied. For example, participant demographics, question wording, or response bias could confound the results. It is important to identify and control for these variables to ensure accurate and reliable data analysis.
What is a factor that can change in an experiment called?
A variable.
What does a correlation coefficient of 0.8 mean?
It means that there is a strong positive association between changes in the two variables being studied. Positive association means that the two variables tend to increase together or decrease together. Note that there is no mention of a causal relationship between the variables.
What is the outcome variabe?
The outcome variable is the dependent variable in a statistical analysis that is being measured or predicted based on changes in other variables, known as independent variables. It is the variable of interest that is being studied to understand its relationship with other variables.
Would the absence of independent variable imply a cause and effect relationship between 2 variables?
No, it would not. It is possible that the statistical model is under-specified and that the variables being studied are all "caused" by another variable.
What is the term for concepts in a study such as the average age of a person up on acquiring his or her first job and the average salary he or she was paid for that job?
Those concepts are referred to as variables in a study. In this case, the variables are the average age of a person upon acquiring their first job and the average salary they were paid for that job. These variables can be studied and analyzed to draw conclusions or make predictions.
When an experimental shows that one variable makes another variable change and no variables have any affect the experiment shows?
The experiment shows a causal relationship between the two variables, where changes in one variable directly impact the other without interference from any other variables. This suggests a clear cause-and-effect relationship between the variables being studied.
