BIOE: WEEK 4 Flashcards
1
Q
At the conclusion of this unit, the students are expected to:
* describe the different measures of
A
- central tendency
- dispersion
- location
2
Q
interpret summary measures such as
A
- mean, mode, median
- range, variance, standard deviation and coefficient
variation - quartile, decile, and percentile
3
Q
- refers to “center” of the distribution of observations
A
Measures of Central Tendency
4
Q
also known as average
A
(Arithmetic) MEAN
5
Q
- middle most value in a set of observations put in an array
- if odd: middle most observation
- if even: mean of 3 middlemost observation
A
MEDIAN
6
Q
- always exists and is unique
A
MEDIAN
7
Q
- most frequently occurring value in a set of observation
A
MODE
8
Q
- gives information as to the tendency of values to clump together
- tools describing the variability of the observations
A
Measures of Dispersion
9
Q
- simplest measure of location
- formula
= highest observation – lowest observation
A
RANGE
10
Q
- measure of variability that takes the mean as the reference point
A
VARIANCE
11
Q
- unit is the same as that of the original set of observations
A
STANDARD DEVIATION
12
Q
- expresses the SD as percentage of mean
A
COEFFICIENT VARIATION
13
Q
- determines the location/ position of particular value in an array of
distribution
A
Measures of Location
14
Q
- points of distribution that divides the observation into 4 equal parts
A
QUARTILES
15
Q
points of distribution that divides the observation into 10 equal parts
A
DECILES
