When: every five years on October 20.
World Statistics Day (English: World Statistics Day)is a special day because once every five years, 20 October is dedicated to statistics on this day and has been so since 2010.
This day is an official United Nations Observance. This means it is a day recognised by the United Nations (UN) and returns every five years. The website about this day only shows little information about it. Only just before the day takes place will the website be updated.

The importance of statistics

Statistics play a crucial role in various aspects of our lives. They provide insight, support decision-making and help in understanding complex phenomena. This text will explore the value of statistics and discuss their impact in different areas.

Decision-making and policy

Statistics are essential for policymakers, business leaders and individuals when making decisions. They help identify trends, predict future developments and evaluate the effectiveness of measures. For example, when setting public policies such as health care or education, accurate statistics are needed to understand the population’s needs and find appropriate solutions.

Scientific research

Statistics are the backbone of scientific research. They help researchers analyse data, test hypotheses and draw conclusions. Whether in clinical trials, environmental research or economic studies, statistics provide an objective basis for evaluating results and assessing the reliability of findings.

Operations and marketing

Companies rely on statistics to measure and improve their performance. They analyse sales figures, customer satisfaction and other relevant data to make strategic decisions. Marketing departments use statistics to identify target groups, optimise campaigns and measure advertising effectiveness.

Health and medicine

In healthcare, statistics are vital. They help track disease outbreaks, evaluate treatments and identify risk factors. Doctors and researchers rely on statistical analysis to make medical decisions and improve the health of individuals and communities.

Education and research

Statistics are an integral part of the educational curriculum. They help students understand concepts such as averages, variance and correlation. Moreover, statistics are essential for academic research, where they are used to test theories and generate new knowledge.
In short, statistics are not just numbers on a page; they form the basis of our decisions, discoveries and progress. The importance of statistics cannot be overemphasised, and promoting statistical awareness is vital for a healthy society.

Website

Besides the UN website, there is also worldstatisticsday.org. By the way, this website is very similar to the UN website. Again, the information is mostly focused on the previous version, unless the day is approaching. So much for the slogan that generally applies: “Connecting the world with data we can trust.” Of course, that’s very lame. Surely we can trust the data. Only it is no longer relevant when it comes to a day that was two or four years ago, right? Or maybe even longer ago…
There’s a Wikipedia page about this day, but it doesn’t give much information more information about this day.
In any case, don’t be fooled: this day is therefore not an annual day.
