Why are measures of variability essential to inferential statistics?
An inferential statement is a conclusion or assertion that is drawn from evidence or reasoning rather than direct observation. It relies on the interpretation of data or information to suggest a broader implication or trend. These statements often involve making predictions or generalizations based on specific instances or patterns observed. In essence, they extend beyond the immediate facts to infer additional meanings or outcomes.
inferential could mean to evolve or you could see the resemblance, or you could also put it like this deduced or deducible.

There is no inferential data. There is inferential statistics which from samples, you infer or draw a conclusion about the population. Hypothesis testing is an example of inferential statistics.
Why are measures of variability essential to inferential statistics?
Evaluative Statements are ATTITUDES (Robbins & Judge; Essentials of Organizational behavior p. 13).
In general in Descriptive Statistics we use tools like central tendency, dispersion, skew, kurtosis to summarize a given set of data. But inferential statistics is much boarder than it. In inferential l statistics we use tools like chi square test, ANOVA, ACOVA, Correlation, Regression, Factor Analysis etc to predict the behavior based on the sample data.
inferential statistics allows us to gain info about a population based on a sample
Inferential statistics uses data from a small group to make generalizations or inferences about a larger group of people. Inferential statistics should be used with "inferences".
it does not use humor
One advantage of inferential statistics is that large predictions can be made from small data sets. However, if the sample is not representative of the population then the predictions will be incorrect.

Level of measurement most inferential statistics rely upon is ratio.
