Countries are sorted by paid work hours in the chart – from highest to lowest. Work is another important activity where we see large differences. In India and the US, at the other end of the spectrum, people sleep an hour more on average. From this sample of countries, South Koreans sleep the least – averaging 7 hours and 51 minutes of sleep every day. We spend the most time working and sleeping and paid work, housework, leisure, eating and sleeping take together 80-90% of the 1440 minutes that we all have available every day.īut if we look closely, we also see some important differences. This is not surprising – most of us try to split our days into “work, rest and fun”, and so there are some predictable patterns.
The first thing that jumps out from this chart is that there are indeed many similarities across countries. The data comes from the OECD and brings together estimates from time diaries where respondents are asked to record the sequence of what they did over a specific day, as well as from general questionnaires where respondents are asked to recall the amount of time spent on different activities on a specific day in the previous week. While some draw a line between creative storytelling and technical analysis, data science merges the two for greater effect.In the chart here we compare average time spent across a number of common activities. Data visualization allows data scientists and other professionals to create a narrative from raw inputs. Data visualization dramatically improves the speed of decision-making. Human beings process visual images like graphs and charts much faster than text. Visualized content is processed faster.Data visualization presents raw data in a clear and cohesive way, which makes it easier to draw informed conclusions and see things from a high-level perspective. The human brain is programmed for visual communication. The human brain evolved to spot patterns, make visual distinctions, and understand the world through narratives, which is why data visualization is so effective.ĭata visualization has many advantages over delivery of raw data: Data visualization is the best technique human beings have for making sense of large datasets.
