Hello y'all. Miss being in the same class as you guys :(
I miss Isfeld so much.
TBO 4 lyf.

Range

Range- The positive difference between the largest and smallest values in a data set.

To find range you must: you take the highest number in the data set minus by the lowest number in the set then it will equal the range.

Quadrant

Quadrant

(+,+) quadrant I (-,+) quadrant II (-,-) quadrant III (+,-) quadrant IV

I = 1,  II = 2, III = 3, IV = 4.

Outliers - Values that are too big or too small compared to the other values.
10,11,12,12,14,98
98, would be an outlier.

Range - Positive difference between largest and smallest values

Mode

The most frequently occurring number in a set of data.


27,65,27,97,65,27
27 would be the mode.

Outcome

Outcome- one possible result of a probability experiment

Range

the positive difference between the largest and smallest values in a data set.

Mode

The most frequently occurring number in a set of data.

Outliers

Outliers - Values that are too big or too small compared to the other values.

Quadrant

(+,+) quadrant I (-,+) quadrant II (-,-) quadrant III (+,-) quadrant IV

Range

the positive difference between the largest and smallest values in a data set

Eg.

range of 4,8,5,6,9,1,3,5,8,6 is

1,3,4,5,5,6,6,8,8,9

9-1 = 8

Quadrant

(+,+) quadrant I
(-,+) quadrant II
(-,-) quadrant III
(+,-) quadrant IV

Mean

A measure of central tendency

the sum of a set of values divided by the number of

values in the set

mean of 6,4,8 is

add up all the numbers and divide the results by how many numbers there are

6+4+8=18

18 divide it by 3 = 6

therefor the mean is 6

Mode

The most frequently occurring number in a
set of data

mode and most both have 4 letters

Eg.

mode of 3,5,7,7,9 is 7

mode of 2,2,4,6,6,8,11 is 2 and 6

Median

The middle number in a set
of data after the data have been arranged in order

Eg.

median of 2,5,6,8,9 is 6

median of 1,3,6,8,9,10 is 7

Median Definition

Definition & How to = Outliers

Outliers: Numbers that have small values and numbers that have large values
How to:
ex . 1 , 99 , 99 , 9001 = 1 & 9001
ex . 16 , 4 , 6 , 9 = 16

Definition & How to = Mode

Mode: Most occurring number on a data set

How to find it:

ex...
6 , 5 , 1 , 5 , 7 = 5


Multiples can occur, even no mode at all.

ex...
7 , 1 , 9 , 2 , 8 ≠ No Mode
6 , 9 , 0 , 6 , 9 = 69 or 6 & 9

Height & Base Definitions

Height or 'h': Vertical distance from the top of an object or figure to its base.
Base or 'b': Surface of an object or the line.
