Box Plot
A 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)
Histogram
A histogram is a type of statistical graph used to evaluate the shape and distribution of numerical data. It divides the sample values into several intervals called bins. The bars represent the number of observations (frequency) that fall within each bin.
Scatter Plot
A scatter plot can be used to observe the relationship between two numeric variables based on the pattern of the scattered points.

Introduction to R & R StudioR (also known as GNU S) is a programming language and software for statistical analysis and graphics. It was created by Ross Ihaka and Robert Gentleman at the University of Auckland, New Zealand, and is now developed by the R Development Core Team, which includes Chambers. R is partially named after its creators (Robert Gentleman and Ross Ihaka) and partially as a play on the name S. R has become the de facto standard among statisticians for developing...

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...

Merge DataMerge Data is an operation that combines data from two data frames that have the same columns or rows. Data merging can be performed using the rbind() function for rows and cbind() for columns in the R programming language. Sort DataSort Data is an operation that arranges data in ascending order (from smallest to largest) or descending order (from largest to smallest). Data sorting can be done using the order() function in R. DatasetDownload Dataset MODULEDownload Module 3

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...

One-Sample Mean TestHypothesis testing regarding the mean can use the Normal distribution (commonly referred to as the Z-test) or the T distribution (commonly referred to as the t-test), depending on whether the population standard deviation (σ) is known or not. MODULEDownload Module 5

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...
