15. Most useful loop structures.
There may be a situation when you need to execute a block of code several number of times. In general, statements are executed sequentially: The first statement in a function is executed first, followed by the second, and so on. Programming languages provide various control structures that allow for more...

14. Discuss relationship between the concept of relative frequency and probability. Note. How defining axioms of probability do correspond to actual properties of the relative frequency
If an action is repeated n times and a certain event occurred b times then the ratio b/n is called the relative frequency. Where as theoretical probability it is used to determine the number of ways that the event can occur if an experiment is repeated a large number of...

13. Find out about the various attempts of intuitive definition of the concept of probability.
Probablity is a way of expressing knowledge or belief that an event will occur or has occurred. The concept has been given an exact mathematical meaning in probability theory, which is used extensively in such areas of study as mathematics, statistics, finance, gambling, science, and philosophy to draw conclusions about...

12. Show the relationships between conditional and marginal frequencies (reasoning on a bivariate distribution) commenting on their meaning.
conditional frequency is it’s a fraction that tells you how many members of of a group have a particular characteristic. More technically, it is the ratio of a frequency in the center of the table to the frequency’s row total or column total. marginal frequency The cells which contain the...

11. Describe the relationship between the concept of “statistic” as function of known data as opposed as to concept of “state of nature” or “parameter” in the unknown population?
There are two meanings to the word “statistic”: - Statistic as a function of known data - Statistic as a science More specifically, regarding the first meaning, statistic (singular) or *sample statistic is any quantity computed from values in a sample, often the mean. Technically speaking, a statistic can be...

10.Describe the similarities and differences between the concepts of “DESCRIPTIVE” and “INFERENTIAL” statistics
Descriptive statistics is that branch of statistics which is concerned with describing the population under study.It quantitatively describes the important characteristics of the dataset. The data is summarised in a useful way, with the help of numerical and graphical tools such as charts, tables, and graphs, to represent data in...

9. The most useful types of collection in visual studio.
ArrayList An ArrayList is a collection from a standard System.Collections namespace. It is a dynamic array. It provides random access to its elements. An ArrayList automatically expands as data is added. Unlike arrays, an ArrayList can hold data of multiple data types. Elements in the ArrayList are accessed via an...

8. Most Common data types in visual studio.
The data type of a programming element refers to what kind of data it can hold and how it stores that data. Data types apply to all values that can be stored in computer memory or participate in the evaluation of an expression. Every variable, literal, constant, enumeration, property, procedure...
