In today's age of information, the use of data is very powerful in making informed decisions. Data analytics is a field that is interested in identifying and interpreting trends and patterns within big data to make data-driven decisions. We focus on informal statistical inference and data modeling as a means of developing students' data analytics skills in school. In this study, we examine how students apply the data modeling process to draw informal inferences when exploring trends, patterns and relationships in a real dataset using technological tools, such as CODAP and Excel. We analyzed 17-18-year-old students' written reports on their explorations of data supplied by third parties. Students used a variety of statistical measures and visualizations to account for variability in analyzing data. They tended to make statements with certainty in their inferences and predictions beyond the data. When the pattern in the data was uncertain, they were inclined to use contextual knowledge to remain certain in their claims.

Secure logical schema and decomposition algorithm for proactive context dependent attribute based inference control
Turan, Ugur; Toroslu, İsmail Hakkı; Kantarcioglu, Murat (2017-09-01)
Inference problem has always been an important and challenging topic of data privacy in databases. In relational databases, the traditional solution to this problem was to define views on relational schemas to restrict the subset of attributes and operations available to the users in order to prevent unwanted inferences. This method is a form of decomposition strategy, which mainly concentrates on the granularity of the accessible fields to the users, to prevent sensitive information inference. Nowadays, du...
Reflections on Turkish Personal Data Protection Law and Genetic Data in Focus Group Discussions
Özkan, Özlem; Şahinol, Melike; Aydınoğlu, Arsev Umur; Aydın Son, Yeşim (2022-12-01)
Since the 1970s and more rigorously since the 1990s, many countries have regulated data protection and privacy laws in order to ensure the safety and privacy of personal data. First, a comparison is made of different acts regarding genetic information that are in force in the EU, the USA, and China. In Turkey, changes were adopted only recently following intense debates. This study aims to explore the experts’ opinions on the regulations of the health information systems, data security, privacy, and confide...
End User Evaluation of the FAIR4Health Data Curation Tool
Gencturk, Mert; Teoman, Alper; Alvarez-Romero, Celia; Martinez-Garcia, Alicia; Parra-Calderon, Carlos Luis; Poblador-Plou, Beatriz; Löbe, Matthias; Sinaci, A Anil (2021-05-27)
The aim of this study is to build an evaluation framework for the user-centric testing of the Data Curation Tool. The tool was developed in the scope of the FAIR4Health project to make health data FAIR by transforming them from legacy formats into a Common Data Model based on HL7 FHIR. The end user evaluation framework was built by following a methodology inspired from the Delphi method. We applied a series of questionnaires to a group of experts not only in different roles and skills, but also from various...
Understanding IMF Decision-Making with Sentiment Analysis
Deniz, Ayca; Angin, Merih; Angın, Pelin (2022-01-01)
With the advances in information technologies, the amount of available data on web sources where people express their opinions increases continually. Sentiment analysis is one of the effective tools for decision-makers to gain insights from massive heaps of data. The field of International Organizations, which produces big data in the form of large documents, has significant potential to benefit from sentiment analysis in decision-making. In this paper, we evaluate the effectiveness of different sentiment a...
Context- and sentiment-aware machine learning models for sentiment analysis
Deniz Kızılöz, Firdevsi Ayça; Angın, Pelin; Angın, Merih; Department of Computer Engineering (2023-1-24)
With the advances in information technologies, the amount of available data on web sources where people express their opinions increases continually. Sentiment analysis supports decision-makers in gaining insights from massive heaps of data. It has gained much attraction recently as it has proven to be a practical tool in a wide range of areas, including monitoring public opinion. Nevertheless, sentiment analysis research is still facing some challenges. One of the main challenges is the irrelevant and redu...
