If you could please locate by providing the URL of these outliers as you find them, we can do our best to take care of them. Thanks.
Links were provided just as you requested. However, after more than two weeks, the obvious errors are still there. Is there nobody that is able and/or willing to fix these?

I have contacted Internet Brands regarding this, and you are welcome to do so yourself as well.

Also, for nearly 1 year now we have been asking for a separate database for the 2008--> and newer Ford Escape Hybrid. It is new enough, and different enough to deserve it's own category. Ford says it is 2-3 MPG better than the 2005-2007's. In the real world, it looks like it is about 5 MPG better than previous model years. I think this ( and every Ford owner will agree ) deserves a separation like the Prius I / Prius II.

Thank You!!!!

Ford / Mercury / Mazda (soon) can be together.
Just pre-2008 and post-2008 need to be separate.
Thanks!

An erroneous, inactive 05 HCH here with one tank at 1.3 mpg: https://www.greenhybrid.com/compare/.../car/5102.html

Two erroneous, inactive Prius IIs
https://www.greenhybrid.com/compare/.../car/4450.html
https://www.greenhybrid.com/compare/.../car/2141.html

An erroneous Vue:
https://www.greenhybrid.com/compare/.../car/5118.html

That's all I could find for now. It's been almost a month since we've addressed these issues, and nothing has happened. Please, can something happen?

These outlier entries probably do affect: mean and standard deviation and standard error

These entries really dont affect: median, middle 50%

the charts show the median, middle 50% so they are unaffected.

Median mpg (US) Mean mpg (US) Middle 50% mpg (US) Standard Deviation Standard Error Cars

Done!

I have a stickied thread in this forum about these issues, so please feel free to post anything else you find there.

It's better if you report issues in my stickied thread, since I get emailed when it's updated and I'm the one who can fix things. If anything, other CarsDirect staff members would wind up forwarding issues to me anyway, so this is faster.

I have other duties, so I won't always be able to fix things right away, but I will get to them as time allows.
