I need to type the symbol for Pearson's Chi-square one time into a paper I am
writing. I could not find it in the available symbols for Word. Please help.
The chi is a lower case Greek letter that is available in almost every "normal"
(non-specialty) font at Unicode value 03C7. In recent versions of Word you can
type 03C7 in the document and then press Alt+X to replace the number with the
character. In all versions, you can use the Insert > Symbol dialog
(
http://www.word.mvps.org/FAQs/General/InsertSpecChars.htm).
The "squared" part is a superscript number 2. You make it by typing the number
2, selecting it, and pressing Ctrl+Shift+= to make it superscript.
Alternatively, you can insert the ² character by typing the number 00B2 and
pressing Alt+X (or, since this symbol is in the original ASCII range, hold down
the Alt key while typing 0178 on the number pad).
