The foundations for this framework are the Principles and Standards for School Mathematics published by the National Council of Teachers of Mathematics [1] [2] [3] (NCTM) in 2000. A second report focused on statistics education at the collegiate level, the GAISE College Report, was published in 2005. Both reports were endorsed by the ASA. [4]
A typical "Business Statistics" course is intended for business majors, and covers [71] descriptive statistics (collection, description, analysis, and summary of data), probability (typically the binomial and normal distributions), test of hypotheses and confidence intervals, linear regression, and correlation; (follow-on) courses may include ...
See also Chrisman (1998), [3] van den Berg (1991). [4] The issue of whether or not it is appropriate to apply different kinds of statistical methods to data obtained from different kinds of measurement procedures is complicated by issues concerning the transformation of variables and the precise interpretation of research questions.
The AP Statistics program addressed a practical need as well since the number of students enrolling in majors that use statistics has grown. [2] A total of 7,667 students took the exam during the first administration, the highest number of students to take an AP exam in its first year. [ 5 ]
Analysis refers to dividing a whole into its separate components for individual examination. [10] Data analysis is a process for obtaining raw data, and subsequently converting it into information useful for decision-making by users. [1] Data is collected and analyzed to answer questions, test hypotheses, or disprove theories. [11]
Test validity is the extent to which a test (such as a chemical, physical, or scholastic test) accurately measures what it is supposed to measure.In the fields of psychological testing and educational testing, "validity refers to the degree to which evidence and theory support the interpretations of test scores entailed by proposed uses of tests". [1]
The Ukrainian system for middle and high school provides grades that lie within 1 and 12. The lowest passing grade is 4. Additionally, the grades are divided into four levels: initial (1–3), sufficient (4–6), average (7–9) and high (10–12).
Early work on statistical classification was undertaken by Fisher, [1] [2] in the context of two-group problems, leading to Fisher's linear discriminant function as the rule for assigning a group to a new observation. [3] This early work assumed that data-values within each of the two groups had a multivariate normal distribution.
