Why must you flip the inequality symbol when?
I suspect you mean the signs < and > meaning "less than" or "greater than". (There is no flip of the inequality sign, which is an equals sign with a line through it). You have to flip when you multiply a "greater or less than" eqequation if you multiply the equatiob through by -1. Example: you have 2>1, and -2<-1.
What is measured by the sign of a z-score?
The sign of the z score is negative if the observation was below the mean and positive if it was greater.
Which one is greater than or lesser than sign?
< less than > greater than To remember which is which, look at the arrows on the number line. <-------------------------------> -3 -2 -1 0 1 2 3 4 5 6 7 8 9 10 The less than sign points to the left. That's where the lower numbers are located on the number line. The greater than sign points to the right. That's were the greater numbers are located on the number line. Just remember the arrows on the number line. Another memory aid is to picture the sign as a little fish-it's always eating the bigger number, and you read from left to right.
How do you find the division sign?
