Excel Analysis

This wiki is designed to help anyone perform statistical analyses on their data using Excel.

Transpose -when copying and pasting, can switch the orientation such that columns become rows/rows become columns Filter e.g., have a bunch of 0s or only want values of 1, can also select unique records only

moving around quickly with keyboard shortcuts: -ctrl+A within section of data, selects all the data only (not the whole worksheet) -ctrl+arrow keys, moves to beginning/end of row/column -ctrl+shift+arrow keys moves and selects to beginning/end of row/column -ctrl+shift+{plus sign} adds row -ctrl+space adds column

Pivot tables -design-> subtotals off, grand totals off -can easily switch ordering

If statements -can contain if statements as well as multiple ANDs and ORs -you can use the not empty logic to preserve empty spaces with your formulas, e.g., =if([datacell] <> "", formula to be applied, "") - this means if the cell is not blank, apply the formula, otherwise leave it blank -isnumber is alternative to the above, as well as istext; other iswhatevers as well There's also countif and averageif commands, etc. useful to only count all the 4s or to average only certain values

Freeze panes -freeze headers in same location so you can see them even when scrolling down

Quick binning of continuous data (e.g., RTs) for histograms using the ceiling command -e.g., =ceiling([cell]/20,1)*20 to place the value into one of twenty bins (?) alternatively, =ceiling([cell],6) to place the value into one of 6 bins (?)

Static referencing in formulas -use the $ sign before row and column reference to keep it static, useful for computing z-scores (better way to quickly do z-scores?)

Note: -copying or duplicating a sheet won't copy over new chart references, the charts will still reference old positions

vlookup -useful for quickly looking up and pasting corresponding values from a table

concatenate -link together two values

autofill a pattern, e.g., given 1 2 3, you can copy and paste 1 2 3 4 5 6 etc. using the little square

graphing -format data series -> add secondary axis -layout -> error bars -> more error bar options (don't use "error bar", it won't give meaningful error bars -confidence intervals can be achived the same way by selecting confidence intervals you've selected

cse -command shift enter, allows formulas to behave like arrays in matlab -sum all values when column n=1 and column i=1, =sum(bla bla) then hit control+shift+enter -average(indirect(aw1&av2):indirect("ak"&aw2))
