Is it motion blur or out of focus?

Out of focus. with an shutter speed that fast you wont have motion blur on this subject. With such a shallow DOF you have to be right on.
I agree with jambulee, at 1/320 of a second, the suspended water should be in focus and certainly the movement of the child would be STOPPED. It's hard to get a good focus on a moving child!
Nice pics though. . . I like the idea of splashing in puddles

You didn't say what lens you used. if it is one of the lenses in your listing then 1/320 shutter speed were more than enough to overcome any but the most violent camera shake. Has to b OOF.
This is true, however nothing seems to be in focus, nada. look at the road surface at all distances it seems to be soft. If it is not camera shake, I don't know the OP's technique, then something should appear to be in focus. Other option is it just needs some sharpening but I am not that familiar with Canon images and how the camera processes them. I know OOC KM/Sony images are usually a bit on the soft side unless you up the sharpening in camera, but I shoot mostly raw so I do not worry about it until post.

Okay, further thoughts bring more questions.
Were you tracking here movement prior to the shot?
If so the overall blur could have been from some movement and the main subject being OOF could be just missed focus. It happens, especially if she was running towards you (hardest movement for the AF to keep up with) With this as has already been mentioned a bit of flash to "freeze" the movement would help but only if the focus was also on. I also would probably go to f8 for a shot like this to expand the window of what is in focus.

i think you are right, maybe he could use servo mode to help lock focus on a moving subject !

Just curious about something.
Were you using the eye piece with elbows tucked? Or the live view with arms extended?

Is there a trick to deciding motion blur vs. out of focus? I think I may have just needed a faster shutter speed. These were both taken at 1/320. The first is F 5.6. The second is F 4.5. They were taken on a 5D mark ii. Thoughts?
It's both got a slight bit of motion blur in the moving parts but it also appears that you missed focus by quite a bit. The house behind her is more in focus than her face is.

Also, the air looks very damp. Any possibility the lens had a slight bit of moisture on it?...condensation perhapes?

Doesn't look like motion blur at such a fast shutter speed. Background looks a bit sharper which makes me think you used the one shot focus instead of Al Focus or Al Servo which will track and follow focus. Cute picture of what little kids like to do when they see a puddle.

Focus. I did something like this when I had turned off autofocus from a previous shoot. Looked ok until I unloaded..... In addition, 1/320 seems plenty fast for action coming at you.

Another consideration is the narrow depth of field. With people focus has to be on the eyes.

The 5D Mark II has had ongoing focus issues since it's release. I have owned two...the second was a replacement for the first, courtesy of the retailer. Neither camera would attain focus while mounted on a sturdy Manfrotto tripod using a Canon 70-200mm f/2.8L IS lens while saving in highest quality JPEG. Shot in RAW, they were fine suggesting a software problem existed in the conversion by the camera to JPEG. It worked fine in JPEG with a 70-200mm f/4.0 without Image Stabilization. There are many reviews relevant to focus issue problems with this camera. I suggest that you might have equipment problems made worse by hand created motion blur. Try pushing the ISO up as high as needed to shoot at a shutter speed of 1/1000 and test under similar conditions. You are not looking at NOISE issues, so evaluate your results for sharpness and see if that helps. You might be surprised at what the higher shutter speeds will do. You need to determine whether you have a blur problem or a camera problem, then fix it. My lens had the IS feature turned off while tripod mounted.
My best wishes for your quick success!

Not sure what your settings are but when shooting children in motion use AF-C continuous and especially when they turn toward you..I now have my D7100 set to AF-c release mode all the time and use back button focus ..when things are stationary I hit the backbutton for focus and take it off and recompose. I never have to switch into AF-s that way. two children makes you adjust quickly..lol
