Use DATA FROM A RANDOM SAMPLE TO MAKE INFERENCES ABOUT A POPULATION Including, but not limited to: Positive rational numbers the set of numbers that can be expressed as a fraction , where a and b are whole numbers and b 0, which includes the – ≠ subsets of whole numbers and counting (natural) numbers (e.g., 0, 2, etc.). Various forms of positive rational numbers Whole numbers Decimals (less than or greater than one) Fractions (proper, improper, and mixed numbers) Data information that is collected about people, events, or objects – Inference a conclusion or prediction based on data – Population total collection of persons, objects, or items of interest – Sample a subset of the population selected in order to make inferences about the entire population – Ex: Ex: Random sample a subset of the population selected without bias in order to make inferences about the entire population – Random samples are more likely to contain data that can be used to make predictions about a whole population. Data from a random sample given or collected in various forms Verbal Tabular (vertical/horizontal) Graphical Inferences based on random sample Qualitative a broad subjective description (e.g., the probability of an event occurring is certain, more likely, not likely, equally likely, or – impossible.) Quantitative a narrowed objective description associated with a quantity (e.g., the probability of selecting a consonant from the word – EXPERIMENT is 1.5 times as likely as selecting a vowel from the same word, etc.) Statistical analysis of data in a random sample to make inferences about a population Ex: Ex: Note(s):
