AdWords doesn't tell you the standard deviation and therefore you're working from a position of zero knowledge. Mean is one, but standard deviation is just as crucial. Standard Deviation The second factor in average position's deceptiveness is that...
In this study, one standard deviation increase in the amount of awe content induced, their chance of being viral increased by 34 percent. Similarly, with one standard deviation increase in the amount of anger content induced, their chance of...
You can then add layers of additional analysis such as calculating the long term mean, variance, and standard deviation. As discussed in the previous tip, calculating standard deviation is an easy way to determine whether the change you see in...
It's a mean, with no standard deviation or skew. If they appear sporadically, they're likely using "standard" delivery. Some awesome things are available, but it's not obvious exactly how to use it to improve your campaigns.

These can quickly be picked out by obtaining the average quality score of each ad group, and then obtaining the standard deviation of all the keyword quality scores of those ad groups. A high standard deviation, say above 2, means keywords with...
Unless you also know your standard deviation and your skew, an average ad position doesn't tell you enough to make any judgements. Red herrings abound when you're looking at your data in AdWords. Information overload is a real risk.
If you're interested, most spreadsheet packages have built-in functions for calculating the mean and standard deviation of a dataset. Standard deviation is a way of measuring the average amount that your data diverges from its mean average.
The numbers are normalised such that the average search volume for each term is marked as 0 and each unit is one standard deviation. For those who need reminding: a standard deviation is the “average” amount by which any data set is removed from...
In this case, I've shown just the primary "anchor-type" chart, as opposed to "by AC Rank" range too, as in each case there was little deviation from the pattern seen with Cotswold Outdoor.com, which is one of natural, proportional decay as AC Rank...
