what is chi-square test of 2X2 table,what we choose for yates correction formula
Wave length can be altered by changing frequency or Energy associated with it
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.
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.
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.
The topography of the land affects where people choose to live. People will not live in areas where they land makes it difficult to survive.
Frequency distribution a mathematical function showing the number of instances in which a variable takes each of its possible values.False

yes a gender is a categorical variable
Categorical.
A quartile.
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.
It is the set of values that a variable can take together with the probability or frequency distribution for those values.
Yes, a stem-and-leaf plot shows the frequency distribution of a variable.
* Probability * Correlation * Validity * Reliability * Variable * Frequency distribution
Yes.
Yes.
Neither. It is a discrete variable.
