Hi list, I took statistics about 5 years before the speech plus came out, and I didn't have an optacon until about 5 years after taking the class; had to do standard deviations and correlation coefficients by hand with the good old Perkins and my math skills. Took me all day to get an assignment done.... But I got an A in the class. I guess the one compensation was that everybody else in the class was told to go to the math lab and use electric calculators since nearly all of them didn't have portable ones yet, so they probably had to stand in line all day. Ah, the good old days of 1971! Mary To unsubscribe at any time, just send a message to: optacon-l-request@xxxxxxxxxxxxx with the word "unsubscribe" (without the quotes) in the message subject.
