Using rolling average for data cleaning / remove outliers
I am looking for a way to average my data, while removing any outliers present. Currently the raw data has time in columns and 16 data points for each time across in a row. I would like to average those 16 data points, but also remove any outliers (+/- 2 standard deviations or ><1.5xIQR is fine).
I've been trying with no luck to come up with a way to:
a) find all the outliers in a range of a 100 rows. The criteria is simply +/- average*2. The outliers can either be above or below.
b) colour the background of these outliers.
c) repeat a&b in the next column.
So in essence, I'm trying to find all values in a table that are twice (positive or negative) that of the average and highlight them.
In this case the outliers for A is 12 and the outliers for B is 4.
Any help, be it in a formula for a given cell, or VBA, is deeply appreciated.
I'm trying to calculate a 3 month average for a set of data but when I type in =average(d2:d4) and drag it down, the next box displays d3:d5 when I need it to take the average of d5:d7. Is there a way I could tweak the formula to do this for me?
I have been assigned a new task, to make a score card for Key Performance Indicators. I have asked the concerned departments for the data.
Now what is this term rolling average/
My data is as follows

How do I get a rolling average? this data is just collected from Jan 2010
I need your assistance working on a large data set that I am working with. I am looking for a restrictive way of identifying the outliers in my data. I am currently using the median and an array formula to identify outliers that are two deviations from the Median Absolute Deviation. This gives me both positive and negative outliers. I used an array formula to distinguish between normal data and an outliers. However outliers shows up for both positive data and negative data. How do I distinguish between the two types of outliers?
Secondly, is there a better approach to finding outliers and how do I go about capturing the data.
