I can't seem to get my calculator into statistics mode. could you please explain it very clear. i must be mising something. i have a texas instrument calculator(Ti-30xA).thank you.


The TI-30Xa does not have a statistics mode. That statistics operations are available at all times, just like addition and subtraction. Just enter the data with Sigma-plus and then calculate the desired statistics---mean, standard deviation, and so forth.

Full details are in the "One-Variable Statistics" section of the guidebook (page 9 in my copy). If you need the guidebook, you can download one from

I cant figure out how to get the square root of a negative number


The square root of a negative number is an imaginary number, and the TI-30XA does not deal with imaginary numbers.

However, the square root of -x is equal to i times the square root of x. So, to calculate the square root of -4, for example, press 4 square_root = and read 2. Thus the square root of -4 is 2i.

How to get the square root using a ti-30xa calculator?


Come on now....there are dedicated "square" and "square root" keys on the TI-30XA....

Enter your number e.g. 4, then press the "root x" key to get 2...

Press "x squared" key to get the square of 2 = 4

There's the even more useful "y to the power x" key and it's inverse "xth root of y" key.

E.g. Enter 2, then press the "y to the power x" key, then 5, then =, answer is 32 (2 x 2 x 2 x 2 x 2). Starting with 32, pres 2nd then the "y to the power x" key, then 5, then =, answer is 2, the 5th root of 32....
