It's an average over ages 15-64. So they're including a lot of people whose work hours are close to 0, which is going to lower the average.

if thats the case then they should had use the median or have a seperate chart of only people working.

I mean, that's how averages work. They're one view of the data, that includes the extreme values. They aren't a complete picture, but they have their value.

In this chart, the exact values aren't what's being showcased, it's more how values compare between countries.

Agree - if all things are equal the percentage differences in say the work hours is what's informative. Although things like a different amount of 15-21 year olds that typically work or don't work in the country will skew the numbers.

You can go down that rabbit hole for years. Unemployment rates in each country will also skew numbers. So can social security/retirement qualifications. For an analysis like this, you have to pick a range, and you have to apply it equally against all test subjects (in this case, countries).

I'd guess they made their choice based on a calculated averages of starting/stopping work.

Yeah. So a question is does this graph provide any useful information? If it were restricted to say persons employed full time between certain ages it would provide information for each country that can be more directly compared.

I think it does. It gives average times spent on certain activities for people aged 15-64 across several countries. As long as you understand what each of the bolded phrases mean and the influence they have on the outcome, it's a very useful and interesting graph.

There's a reason statistics is an entire field. Making assumptions or expecting a graph to say something it isn't is super easy to do.
