• 7. The most important families of theoretical distribution.

    Theoretical distribution is when you know what the distribution is and its parameters Empirical distribution is when we start knowing nothing. What we have is a collection of observations, and we want to try and derive some knowledge from that collection. Continuous distribution Uniform distribution:- is a type of distribution...

  • 6. Distinction between quantitative continuous, categorical, quantitative discrete and appropriate representation

    What are Categorical data? Qualitative variables measure attributes that can be given only as a property of the variables. The political affiliation of a person, nationality of a person, the favorite color of a person, and the blood group of a patient can only be measured using qualitative attributes of...

  • 5. Formal properties of the relative frequency

    A frequency distribution is a distribution that shows how often something happens. with relative frequency distribution, we don’t want to know the counts. We want to know the percentages. Relative frequency of a class = class frequency/n, where Class frequency refers to the number of observations in each class; n...

  • 4. from the data set to the distribution, discuss the loss of information and the gain for interpretation.

    The distribution of statistical data set or population is a listing or function showing all the possible values of the data and how often they occur. Loss of information includes list of the the population(list of names), which means the list of the statistical unit is removed from the distribution...

  • 3. Insight on scale of measurement

    Variables can be classified as qualitative(aka, categorical ) or quantitative(aka, numeric) Qualitative:- qualitative variables take on values that are names or labels(nominal or ordinal). Example hobby of someone(football, boxe, film, music). ### Nominal:- observation can be taken that is not able to organized in logical sequence. Examples of this variable...

  • 2. Explain the concept of data set obtained by a population of statistical units and a set of variables (attributes)

    Data set is a collection of data. In the case of tabular data, a data set corresponds to one or more database tables, where every column of a table represents a particular variable or attribute, and each row corresponds to a given record of the data set in question, which...

  • 1. what is statistics and why it is useful?

    Statistics is the study of both qualitative and quantitative information called data. It is also a discipline that concerns the collection,organization, displaying, analysis, interpretation and presenting data.In addition to that, it is a collection of mathematical techniques that help to analyze and present data. These data are observations, but they...
