In SAS, how does one obtain descriptive statistics of continuous data.
You can use the PROC MEANS statement to get information such as the N, mean, standard deviation, mode, etc. of a variable.
A set of numbers is as follows: 2, 2, 3, 3, 3, 3, 3, 4, 6, 7, 9. What is the mode of the data?
The mode is 3 because because it is the value that appears most often.
Factor the following quadratic equation: x^2 + 11x +24
You can use the FOIL method to factor the equation. FOIL stands for first, outer, inner, and last. Start by making two sets of open and close parentheses. Next, write two Xs in the parentheses, which will be x^2 when multiplied. Two numbers that you multiply together to get 24, as well as add to get 11, are 8 and 3. One set of parentheses should have x+3 and the other should have x+8. Set each equal to 0. The solutions are x = -3, or x= -8.
