Probability of Discrete Random Variables (Binomial Distribution)
The binomial distribution can be used to calculate the probability of a discrete variable with the following characteristics:
- A total of n trials are conducted.
- Each trial results in only 2 possible outcomes, such as success or failure.
- The results of the trials must be independent.
- All probabilities must be the same for each trial.

Box PlotA box plot (or boxplot), also known as a box-and-whisker diagram, is a graphical technique in descriptive statistics used to visually depict numerical data through five measures as follows: Minimum value (the smallest observation) First quartile (Q1), which cuts off the lowest 25% of the data Median (Q2), or the middle value Third quartile (Q3), which cuts off the highest 25% of the data Maximum value (the largest observation) HistogramA histogram is a type of statistical graph used...

Data Preprocessing Using PythonData Preprocessing is an initial stage in data processing before applying machine learning algorithms. The data we typically use in daily life, whether from databases, Excel files, or other sources, is often unstructured (the data is imperfect). For example, a dataset may contain missing values, different data types, and so on. These issues need to be addressed first to make the data we manage easier to handle and to ensure the output meets our expectations. The...

Estimation of Population ParametersThe estimation of population parameters discussed here is limited to the case of estimating the mean of a population for numerical data and estimating the proportion of a population for categorical data. The population mean (µ) is estimated by the sample mean (x̅ or x-bar) ± MOE (margin of error). The population proportion (p) is estimated by the sample proportion (p̂) ± MOE. A simple illustration is in the case of estimating the pH level of bottled drinking...

Data Exploration Using PythonHistograms are useful for providing an overview of the measures of central tendency and the symmetry of observed data. Another graphical presentation that can summarize more detailed information about the distribution of observed data values is Box and Whisker Plots, often referred to simply as BoxPlots. As the name suggests, Box and Whisker consists of a Box and whiskers. A box-plot or boxplot (also known as a box-and-whisker diagram) is a graphical representatio...

Data TypesIn programming languages, data types are categories that define the nature of data based on the logical operations that can be performed on them. Data types can be divided into several categories, including Character, Numeric, and List types. There are also complex data types, such as Data Frames. In the R programming language, there are various data types that can be used for analysis. Additionally, data types in R share similarities with those in older programming languages, such ...

Wilcoxon Signed-Rank Test and Wilcoxon Rank-Sum TestThe Wilcoxon Signed-Rank Test (WSRT) is a part of non-parametric statistical tests that can be used for paired sample cases. Non-parametric statistics, also known as distribution-free statistics, do not require the assumption of a normal distribution for the population and can be used for small sample sizes. Null Hypothesis (H0): There is no difference in average performance between the two groups.Alternative Hypothesis (H1): There is a diff...
