Python range() Function Built-in Functions. It is a commonly used measure of variability.

They always take parentheses.ĭomain of #f(x)=sqrtx# is #[0, oo)#" "#(sqrt0 = 0# is a number.)ĭomain of #g(x)=1/sqrtx# is #(0, oo)#" "#(1/sqrt0# is a not number. In statistics, the range is the spread of your data from the lowest to the highest value in the distribution. They are not endpoints, but indicators that there is no endpoint. The symbols #-oo# (and #oo#) are used to indicate that there is no left (right) endpoint for the interval. Of course, mixed intervals #(a,b]# or #[a,b)# are also possible. People sometimes say this is #4# to #9# "inclusive" (Including the endpoints) So there are 13 possible scores on that section, and the score range is 0-6. However, Analytical Writing, the essay section, is scored from 0-6 in half-point increments. 130 is the lowest possible score, and 170 is the highest. # includes #4# and every number from #4# up to #9#, and it also includes #9# So, the GRE score range is 130-170 for the main sections of Verbal Reasoning and Quantitative Reasoning. People sometimes say this is #3# to #7# "exclusive" (Excluding the endpoints) It also includes numbers greater than #3# and less than #7#, but it does not include 7. Parentheses are like strict inequalities. So, you look at how low and how high the graph goes. Range is all the values of Y on the graph. There can be very large values for X to the right. So, you need to look how far to the left and right the graph will go. Use a bracket (sometimes called a square bracket) to indicate that the endpoint is included in the interval, a parenthesis (sometimes called a round bracket) to indicate that it is not.īrackets are like inequalities that say "or equal" Domain is all the values of X on the graph.
