    statistics (Goldstein, 2011; Gay, 2010; Snijders & Bosker, 2012). There are two types of statistical operations to which research data can be subjected for making of appropriate inferences about the population from the sample. They are parametric statistics and nonparametric statistics. It must be reiterated emphatically that of these two, the parametric statistics is incomparably more powerful, sensitive, appropriate, accurate and suitably desirable classically. A more powerful statistical test

For example: if a teacher wishes to determine the exam score that divides his class in half, with 50% scoring above and 50% scoring below, he determines the point that marks the 50 percentile. In statistics, there are percentile scales which have special names for various percentiles. Deciles are percentiles which divide a distribution into ten equal sections. There are nine deciles in each distribution of values which correspond to the 10th, 20th

    Identifiability is a crucial property in statistics, as it is a primary requirement for models in order to be correctly estimated. A statistical model is a collection of probability distributions. A model can be defined by a function from a set of parameters: in this case it is called parametric model, and the function itself is called parametrization map. Identifiability is a ‘’good property” for the parametrization map: a model is identifiable if this function is one to one, that is, each probability

    statistical techniques called nonparametric, or distribution-free, techniques are used. Nonparametric statistics are based on fewer assumptions about the population and the parameters than are parametric statistics. Sometimes they are referred to as distribution-free statistics because many of them can be used regardless of the shape of the population distribution. A variety of nonparametric statistics are available for use with nominal or ordinal data. Some require at least ordinal-level data, but others

    The significant figures in a number are the digits that contribute to the precision of its value. Since measurements are approximations, significant figures are critical when reporting data because it demonstrates to what precision the data was measured. As a result, certain rules must be set into place to determine which digits in a value are significant and how to calculate values that express the correct number of significant figures. For numerical values, there are rules set to in order

    Statistics is the gathering of information identified with a subject. As a matter of fact, the two major branches of statistics, descriptive and inferential statistics. In addition, statistics gives the mechanics to lowering the aftereffects of numerous, measurement into a tiny set of quantities that describe all of the raw data/ information, and furthermore gives the metrics to evaluate how suitable those quantities are at categorizing the raw data. With that being said, both descriptive and inferential
