“…EDA aims to comprehend data structure and patterns, serving multiple analytical purposes, including identifying outliers, detecting data deviations, determining crucial variables, suggesting hypotheses, and uncovering hidden patterns [25]. Statistical analyses or graphic representations can be deployed to address hypotheses built with EDA [26]. Specific techniques, such as measures of frequency, central tendency, and dispersion, were applied to the dataset for quantitative data, with the calculation of frequency and proportion applied for qualitative data.…”

The advent of air travel, originally proposed by the Wright brothers, has led to a significant surge in aircraft usage for human transportation. In its nascent stages, this mode of transport was linked with a high frequency of accidents and consequent fatalities, placing it in the high-risk category. To counter these risks, the International Civil Aviation Organization (ICAO) was established in 1947 as a collaborative effort among numerous countries with the primary goal of enhancing aviation safety regulations. This study analyzed archival data from the Bureau of Aircraft Accidents Archives (B3A), covering a span of 72 years from 1918, the year of the first commercial airplane crash, until 2020. The objective was to understand the ICAO's impact on altering accident rates, fatalities, and underlying causes. Analytical methodologies encompassed both descriptive statistics-examining data distribution, central tendencies, and category frequencies-and exploratory data analysis (EDA) to identify variable relationships and outlier identification. The results indicated that ICAO's interventions have led to a notable decline in accident rates, with an annual average reduction of 70.9%, and a corresponding decrease in incidents attributed to technical factors. However, an unexpected trend was the increase in fatalities despite the drop in accident numbers, attributable to the introduction of larger aircraft designs carrying more passengers per flight. The findings underscore the ICAO's successful efforts in reducing aircraft accidents, but also suggest a need for further exploration into factors contributing to the rise in fatalities.

“…With increased interactive statistical 12 and defined visualisation tools, 13 visualisation has become inevitable part of EDA. Methods for visualising temporal data 14 and algorithm-based methods, such as Self-Organising Maps (SOM) 15 and uncharted forest-based 16 visualisation techniques, are explored widely in recent years. The generated DAMADICS data set was subjected to three layers of visualisation techniques.…”

This article illustrates the importance of exploratory data analysis as the key step in the data validation process and also for further model development. Descriptive statistics is performed by applying the exploratory data analysis approach to a data set that is derived from the simulink library of a benchmark industrial actuator process provided by the Development and Application of Methods for Actuator Diagnosis in Industrial Control Systems research group. In this work, the data set is synthetically generated from an actuator model by simulating it under different fault conditions. The exploratory data analysis is performed as an initial investigation on the data set to reveal the anomalies and patterns for making suitable assumptions and test hypothesis to develop more accurate models. The raw data are visualised using different visualisation techniques to find patterns and behaviours. The data distribution, class distribution, feature correlation and presence of outliers are revealed through data visualisation. Data processing is performed to transform the data, and treat outliers and missing values in the data set. The treated data set after performing data processing is visually confirmed using appropriate visualisation techniques. The inferences from the visualisation methods are validated quantitatively with statistical results to support the exploratory data analysis. Data profiling is dealt with by collecting the metadata on the Development and Application of Methods for Actuator Diagnosis in Industrial Control Systems data set and aids in enhancing the data set quality and content to procure accurate predictive models employed to foresee the actuator performance.

This study aimed to assess the impact of establishing a regulating agency to protect public safety in air transportation (ICAO). In the implementation, we gather a database from BAAA, which is then converted into a dataset for analysis with descriptive statistics and EDA. To see the aim of the analysis, divide the time before and after the foundation of ICAO so that the analytical method based on the number of accidents and casualties is compared before and after the establishment of ICAO. In terms of the outcomes, the data show that there has been a decrease in the number of accidents since the establishment of ICAO. This means that the ICAO has a positive impact as an organization in protecting passengers or customers.
