Reply to comment by GTthrowaway27 in The average TikTok user in the US is an adult 'well past college age,' CEO says by djJAMZ

It still skews the question of; what age groups are using tik tok?

Of course. Mean and media won’t be exact unless it’s normal, bimodal, etc

But why act as though it’s going to be a meaningful difference?

The CEO is saying the average user is older than you would assume(teenagers/college). That’s it. Even if the median and mean are different by several years, that’s still generally going to be the same point.

It just seems the easy Reddit contrarian point of “um aktually median is better” (hence multiple comments saying the same thing) when they’re probably not that much different to begin with

I can assure you that if the median age was higher than the mean, TikTok would have used that.

Just a pet peeve that Reddit assumes median is always a better representation when we don’t have the actual distribution

In this case, do you assume the mean is a better representative than median (without distribution data)?

No but I’m saying in this example it doesn’t really matter because it doesn’t need to be precise

The skew of the data matters a lot. The tail on the upper end extends much further than the tail on the lower end which means that the data will more than likely skew right. That would make the median lower than the mean. How much lower depends on the skew of the data but there is a huge difference between a median of 16 and an mean of 25 compared to a median of 22 and a mean of 25.
