Programming on R software (Data manipulation, analysis and visualization)

From 39 € /h

R software is one of the most powerful and flexible statistical software, in addition to being completely free! Its use can be intimidating at first, however.

Whether you need help solving a specific problem (e.g. restructuring a database, performing a statistical test, plotting a graph, etc.), or you would like to learn how to use this monitoring software. more generally, I suggest you put my more than 6 years of experience with R at your service.

About Me

I have already taught a lot and I love to do it, especially statistics. From experience, I know that statistics seem difficult and boring when you don't see their practical usefulness. When I teach, I therefore put a lot of effort into making the material concrete by showing its practical implications!

If you want to know more about me:
I have a doctorate in social sciences. My work and my training (Master in Social Psychology) are largely based on sophisticated statistical analyzes, so I had the opportunity to go around the subject!

Private lessons in statistics and data analysis in Brussels (for psychological and social sciences)

38 € /h

If you have difficulties in statistics, I can help you! My courses are aimed at students of higher education or doctoral students in psychological and social sciences, or anyone interested in understanding statistics. My teaching method fully adapts to your needs. I would therefore ask you for a brief description of the objective that you set for adapting my courses accordingly. Depending on your needs, my courses can cover:

- The theoretical bases of descriptive and inferential statistics

- The most common inference tests (Chi-square, T test, ANOVA, linear regression, etc.) or more sophisticated (multi-level analyzes, structural equations) or other data organization tools (factor analysis, analysis in clusters).

- Application on SPSS, Jamovi, JASP and R software

- Practical exercises with data provided by myself, or your own data.

In any case, I will go into the details of these different subjects only according to your needs / interests and my explanations will be clear and understandable regardless of your level :)

Math teacher gives private lessons in math-statistics and probability.

My teaching has already proven itself with several students that I have already followed and that I continue to follow. It consists of short-term help in overcoming the difficulties of a project or of certain chapters, just as it also consists of continuous monitoring to give students the means to play a role in their successes. The main goal is not to learn selfishly, but to teach the student how to manage his time and his way of working: these points are very important for success in these studies continuously.
my course is for students:

> Secondary: I offer a lesson to the students + the exercises
> Central jury: I offer a course to students, work on exams from previous years
> Entrance exam of medicine and polytechnic .: I offer a course support to students, cards, summaries, qcm.
> Higher education students: statistics and probability: descriptive statistics, probability, inferential statistics (binomial, normal, Poisson, sampling-estimation, confidence intervals, statistical tests (hypotheses) chi-square test, Anova.etc).

MIT App Inventor is a visual programming environment that enables everyone to build apps for smartphones and tablets.

The course for beginners does not require any previous programming experience. It starts with an introduction to the App Inventor interface. Then, after Event-Driven Programming is explained, learners will discover the available command blocks which they will have to combine to make their own apps. During this course, learners will have the opportunity to use their imagination and practise analytical and critical thinking to create their own apps such as animations, games, quizzes, tourist guides or drawing apps.

This course also aims to engage intermediate or even advanced App Inventor programmers who can build on their previous experience to create more sophisticated apps.

The content and pace of the course is adapted to the age and needs of the learners.

Mathematics can often feel complex and overwhelming, but with the right approach, it becomes much more manageable and even enjoyable. My goal as a tutor is to help students not only understand the material, but also find the learning method that works best for them.

I work with students at school level, SAT level, and university level, supporting them in building a strong foundation and progressing confidently through their subjects.

My teaching approach begins with identifying each student’s gaps in understanding. I then provide clear explanations using simple language, structured steps, and relatable examples. Once the concept is understood, I guide students through practice, allowing them to apply what they’ve learned and develop real confidence in problem-solving. Many of my students see improvement within a few lessons.

I also create personalized exercises tailored to each student, helping reinforce knowledge and target specific weaknesses.

Beyond improving grades, I focus on helping students:
• Gain confidence in mathematics
• Develop logical and structured thinking
• Learn how to approach problems effectively

Having worked with students from diverse backgrounds and levels, I adapt my teaching style to each individual, ensuring that every student feels supported and motivated.

My aim is not only to help students succeed academically, but also to help them better understand how they learn and approach challenges with confidence.

Do you have a statistics or probability exam in BA1/BA2? I can help you review the material in a clear, structured and exam-oriented way.

I support higher education students (university and college), particularly in their first and second years of undergraduate studies, to understand important concepts, redo practical exercises, and practice with exam-style questions.

My goal is simple: to help you understand the logic behind formulas, know when to use them, recognize correct reasoning in a statement, and gain autonomy when facing exercises.

Subjects covered according to your program:

• Descriptive statistics:
mean, median, variance, standard deviation, quartiles, quantiles, coefficient of variation, box plots, histograms, graphs, interpretation of tables and data.

• Univariate and bivariate statistics:
analysis of one variable, analysis of two variables, scatter plots, covariance, correlation, regression line, coefficient of determination, interpretation of relationships between variables.

• Probabilities:
events, union, intersection, complement, conditional probabilities, independence, Bayes' theorem, probability trees, contingency tables.

• Combinatorial probabilities:
permutations, arrangements, combinations, draws with or without replacement, counting, classic exam situations.

• Random variables:
discrete and continuous variables, probability function, density function, distribution function, expectation, variance, standard deviation, variable transformation.

• Probability laws:
Bernoulli distribution, binomial distribution, normal distribution, standard normal distribution, Student's t-distribution, chi-square distribution, use of statistical tables according to your course.

• Statistical inference:
sampling, estimators, point estimation, confidence intervals, margin of error, degrees of freedom, confidence level.

• Hypothesis testing:
null hypothesis H0, alternative hypothesis H1, significance threshold, p-value, one-tailed or two-tailed test, test on a mean, test on a proportion, chi-square test, interpretation of results.

• Exam preparation:
reading statements, choosing the right method, identifying the formulas to use, typical exercises, past exams, guided corrections and problem-solving methods.

Method of working :

1. We quickly identify the chapters that are causing problems;
2. I re-explain the theory with simple examples;
3. We redo the important exercises together;
4. I will show you how to recognize good reasoning in the exam;
5. We construct a clear method that can be reused independently.

I don't just provide a correction: I explain the reasoning step by step so that you are able to redo the exercises without help.

For students retaking the exam, I also offer more intensive support: level assessment, priority identification, review of fundamentals, and practice with typical exercises and past exams. The goal is to get straight to the point and work efficiently within the time available before the exam.

I have been giving private lessons for over 7 years in mathematics, statistics, economics, and accounting. I have also tutored first and second-year Bachelor's students at Solvay/ULB in mathematics, statistics, and microeconomics as part of a university tutoring program.

My professional experience in finance and business controlling at Deloitte has also allowed me to develop a very structured approach to numbers, analysis and problem-solving.

Courses available in French or English, online or in person in Brussels or the surrounding area.

The world around us is becoming increasingly digital, and artificial intelligence is playing a growing role in our everyday lives. Yet, it is not always easy to understand how these technologies work or how to use them effectively.

I have a degree in Business Engineering and Information Systems and currently work as a Data Scientist. I am also interested in application development, programming, and artificial intelligence more broadly. Through my courses, I would like to share my knowledge in a simple, practical, and accessible way, adapted to each learner.

The lessons are fully personalized according to your level, goals, and interests. For example, we can:
- introduce a child or teenager to programming;
- learn the basics of programming or explore more advanced concepts;
- discover artificial intelligence and understand how it works;
- learn how to use tools such as ChatGPT or Claude effectively;
- or simply become more comfortable using computers, smartphones, and digital tools.

No prior knowledge is required. Whether you are a complete beginner, already comfortable with technology, or simply curious to learn more, we can create a course together that matches what you want to learn, at your own pace.
