• 3. ESTADISTICA INFERENCIAL ESTADISTICA DESCRIPTIVA E INFERENCIAL Es el número total de grupos en que se clasifica la información, se recomienda que no sea menor que 5 ni mayor que 15 Marca de Clase: Es el punto medio del intervalo de clase, se recomienda observar que los puntos medios coincidan con los datos observados para minimizar el error. Glossary: Population: A population is the collection of inter-breeding organisms of a particular species, or similar features. Sample: in statistics, a sample is a subset of a population. Typically, the population is very large, making a census or a complete enumeration of all the values in the population impractical or impossible. The sample represents a subset of manageable size Sampling: Is that part of statistical practice concerned with the selection of an unbiased or random subset of individual observations within a population of individuals intended to yield some knowledge about the population of concern, especially for the purposes of making predictions based on statistical inference. Sampling is an important aspect of data collection. Variable: A letter that represents a value in a algebraic expression,can be used to measure. Inference: is the process of drawing a conclusion by applying clues (of logic, statistics etc.) to observations or hypotheses; or by interpolating the next logical step in an intuited pattern. The conclusion drawn is also called an inference. The laws of valid inference are studied in the field of logic. Class interval: In statistics, the range of each class of data, used when arranging large amounts of raw data into grouped data. Range: Mtra. A Elsa Retureta Álvarez Página 3
• 4. ESTADISTICA INFERENCIAL ESTADISTICA DESCRIPTIVA E INFERENCIAL In descriptive statistics, the range is the length of the smallest interval which contains all the data. It is calculated by subtracting the smallest observation (sample minimum) from the greatest (sample maximum) and provides an indication of statistical dispersion. Class mark: The mid-value of a class interval, or the integral value nearest the midpoint of the interval. Mtra. A Elsa Retureta Álvarez Página 4
