What is the term used to describe the spread of values of a variable?
The term used to describe the spread of values of a variable is "dispersion." Dispersion indicates how much the values in a dataset differ from the average or mean value. Common measures of dispersion include range, variance, and standard deviation, which provide insights into the variability and distribution of the data.
What is the variable for wavelength?
Wave length can be altered by changing frequency or Energy associated with it
How many type of variable?
This question could be answered in a variety of ways. In statistics for the biological sciences we use scales of measurement for variable types. In this case there are 4 types of variables: nominal (aka categorical), ordinal, interval (aka scale), and ratio.
Definitions of the 3 types of variables in doing an experiment?
The three variable in an experiment are independent, dependent, and controlled. The independent is the variable you control, the dependent is the variable that will change according to the independent. The control is kept constant so they do not affect the dependent.
What are the different variables during an experiment?
categorical variablesquantitative variablesordinal variablesthere are more common ones like...Controlled/constant variable-Variables that do not change at all!Manipulated/independent variable-Variables that change (intentionally) in order to see their effect on another variable.Responding/depending variable-Is measured quantitatively or qualitatively and is affected by the independent variables.Hope this helps.
Is a frequency distribution a way to describe numerical data categorically?
Frequency distribution a mathematical function showing the number of instances in which a variable takes each of its possible values.False

What is commulative frequency distribution?
The cumulative frequency distribution for a value x of a random variable X, is a count of the number of observations in which X is less than or equal to x. The cumulative frequency distribution for a value x of a random variable X, is a count of the number of observations in which X is less than or equal to x. The cumulative frequency distribution for a value x of a random variable X, is a count of the number of observations in which X is less than or equal to x. The cumulative frequency distribution for a value x of a random variable X, is a count of the number of observations in which X is less than or equal to x.
What does data distribution mean?
It is the set of values that a variable can take together with the probability or frequency distribution for those values.
Do stem-and-leaf plots show frequency?
Yes, a stem-and-leaf plot shows the frequency distribution of a variable.
What type of variable is colour?
Color is considered a categorical variable.
Is religion a categorical variable?
Yes.
Is diet a categorical variable?
Yes.
Is number of children a continuous variable or categorical variable?
Neither. It is a discrete variable.
What is the difference between continuous and categorical independent variables?
A categorical variable (also known as a discrete variable) is one whose range is countable; e.g. the variable answ has values [yes, no, not sure]. answ is a categorical variable with range 3.A continuous variable is one which is not categorical; e.g. weight is a continuous variable which can take any value between 0 and 1000 kg (say) for a human being.
