key statistical concepts

②
Population : an entire collection of individuals about which we want to draw conclusions .




②
Census : the collection of information from the whole population .




②
Sample : a subset of the population which should .




②
Survey : the collection of
information from a sample .




②
Data : information about individuals in a population .




②
Categorical variable ( qualitative) : describes a particular quality / characteristic which can be divided into categories .




②
Numerical variable ( quantitative) : describes a characteristic which has a numerical value which can be counted or measured .




Discrete numerical variable : exact number values → result of counting .




Continuous variable : values within certain result of measuring
→
a
range .




②
Parameter numerical quantity measuring aspect of the
:
a some population .




②
Statistic quantity calculated from the data gathered
:

from a sample → to estimate a
parameter .




②
Distribution the pattern of :
variation of data .




②
Outliers : data values that are either much
larger or much smaller than the
general body of data .

Measuring the center of data -
central tendency
Model discrete ) 1 Modal class ( continuous) : most frequently occurring value in the dataset .




Mean : statistical the arithmetic sum of all data values
name for average . mean =
the number of all data values
2 outliers use when

Median : middle value of an ordered dataset .
median = ntl

Exercise 2313.1

2. a. Mean dataset A : 6.46 b. Median data set A : 7 . c. The mean of dataset A is less than the mean of data set B.


Mean dataset B 6.85 : Median data set B : 7 .
since the Max value in dataset A is lower than the max value of

data set B.


d. The medians are the same for both datasets since 7- is


the middle value of the ordered dataset .
