Significant variables are the variables whose change will alter or affect the outcome of the experiment. Variables that are not significant may also alter the outcome, but this change is a statistical error, not a systematic change. For example if you are trying to estimate how much food will be consumed in an event, a variable is how many people will attend the event and another is how tall are the people that attend it. The first variable is significant, whereas the latter isn't.

Significant variables are those that have a strong impact on the outcome of a study or analysis. They are usually the focus of the research and are considered important in understanding the relationships between different factors. Identifying significant variables helps researchers draw meaningful conclusions and make informed decisions based on their findings.

Which three variables does the author recognize as being especially significant in determining one's social class?
The three variables recognized by the author as significant in determining one's social class are income level, education level, and occupation. These factors often work together to influence a person's social status and opportunities within society.
What is significant difference?
A significant difference refers to a statistically meaningful distinction between two or more groups or variables. It implies that the difference observed is unlikely to have occurred by chance and is likely to have practical relevance. Statistical tests are used to determine if a difference is significant.
What are the three demographic variables?
The three demographic variables commonly used are age, gender, and income. These variables help categorize and identify characteristics of a population for research and marketing purposes.
Does qualitative research not control variables?
In qualitative research, researchers do not typically control variables in the same way as in quantitative research. Instead, they aim to explore and understand the complexities and nuances of a phenomenon without manipulating variables. The focus is on gaining in-depth insights and understanding the context in which the research is conducted.
What are the three most important variables in determining one's place in the social stratification system?
The three most important variables in determining one's place in the social stratification system are income, education level, and occupation. These factors contribute to an individual's social status and access to resources and opportunities within society. Additionally, factors such as race, gender, and geography can also play a significant role in shaping social stratification.
What was significant about the organisms Darwin observed on the Galapagos Islands?
because he discovers the differences between the variables of finches
When is there no trend line for a scatter plot?
When no possible relationship between the two variables in question is statistically significant.
Why is density expressed in two significant figures?
Because density expressed in two significant figures depends on your accuracy of your measurements of mass and volume to calculate as well as any variables that you are expected to use.
The causes of muticolinearity in multiple regression?
There is multicollinearity in regression when the variables are highly correlated to each other. For example, if you have seven variables and three of them have high correlation, then you can just use one them in your dependent variable rather than using all three of them at the same time. Including multicollinear variables will give you a misleading result since it will inflate your mean square error making your F-value significant, even though it may not be significant.
Mary somerville's most significant contributions to the field of mathematics?
Mary Somerville was a Scottish mathematician and astronomer. She contributed many things to the mathematic world, but her invention of the commonly used variables for algebraic math is the most significant.

What is the meaning of declare value?
When forming a hypothesis for quantitative research, a declarative hypothesis states the expected relation between variables, whereas a null hypothesis states that there is no significant relation.
How many variables are tested during an experiment?
There are three types of variables tested: manipulated variables, controlled variables, and experimental variables.
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 variables that do not change in an experiment?
Variables that do not change in an experiment are independent variables.
The variables that do not change in an experiment are what?
Variables that do not change in an experiment are independent variables.
