  • Catch up with the lesson yourself

10
Miss a SAC or an outcome test?
  • Bring
  • A medical certificate

Ch 1 Organising Displaying
Data
  • CLASSIFYING DATA
  • Categorical a category is recorded when the data
    is collected.
  • Nominal group has a name eg gender,
    nationality, occupation,
  • Ordinal group has a name which can be ordered
    eg low, medium, high shoe size
  • Numerical when data is collected a number is
    recorded.
  • Discrete data is counted.
  • Continuous data is measured

17
Numerical Data
  • Two types of numerical data
  • Discrete the numbers recorded are distinct
    values, often whole numbers and usually the data
    comes from counting. Examples include number of
    students in a class, pages in a book.
  • Continuous any number on a continuous line is
    recorded usually the data is produced by
    measuring to any desired level of accuracy.
    Examples include volume of water consumed, life
    of a battery.

18
Q1 Answer True or False
  • The age of my car is numerical data

True False
19
Q2 Answer True or False
  • The colour of my car is categorical data
  • True
  • False

20
Q3 Answer True or False
  • The number of cars in the car park would be
    considered numerical continuous data.
  • True
  • False

21
Q4 Answer True or False
  • If I rate my driving experience of some test cars
    between one and ten, this is considered numerical
    discrete data.

True False
This is an example of categorical data
22
Q5 Answer True or False
  • Continuous numerical data can be measured

True False
23
Q6 Answer True or False
  • If 1 satisfied, 2 indifferent 3
    dissatisfied, I am collecting categorical data

True False
24
WARNING
  • It is not the Variable NAME itself that
    determines whether the data is Numerical or
    Categorical
  • It is the WAY the DATA for the VARIABLE is
    recorded
  • Eg weight in kgs
  • Eg weight recorded as 1 underweight,
  • 2 normal weight, etc

25
Univariate Data
  • Summarising data
  • Frequency tables may be used with both
    categorical and numerical data.
  • Class intervals are used to group continuous
    numerical data or to group discrete data where
    there is a large range of values.

26
Categorical Data
FAVOURITE TEAM FREQUENCY FREQUENCY
Collingwood 12 12/35 100 34
Essendon 5 14
Bulldogs 15 43
Carlton 3 9
TOTAL 35 100
27
Categorical Data Bar Graph / Column Graph
28
Percentaged Segmented Bar Chart
29
Describing a Bar Chart
  • We focus on 2 things
  • The presence of a DOMINANT Category in the
    distribution given by the Mode
  • The order of Occurrence of each category and its
    relative importance
  • REPORT where you comment on features. Use
    percentages to support any conclusions

30
Organising Displaying Numerical Data
  • Group the DATA
  • Guidelines for choosing the number of Intervals
  • Usually use between 5 and 15 intervals

31
Numerical Data
NUMBER OF SIBLINGS FREQUENCY PERCENTAGE FREQUENCY
0 2 2/25100 8
1 4 16
2 12 48
3 7 28
25 100
32
How has forming a Frequency Table helped?
  • Orders the data
  • Displays the data in compact form
  • Shows a pattern way the data values are
    distributed
  • Helps us to identify the mode

33
Numerical Data Histogram
  • There are no spaces between the columns of a
    histogram

34
Numerical Data Stem and Leaf Plots
  • Stem and Leaf Plots display the distribution of
    numerical data (both discrete and continuous) as
    well as the actual data values
  • An ordered stem and leaf plot is obtained by
    ordering the numbers in the leaf in ascending
    order.
  • A stem and leaf plot should have at least 5
    numbers in the stem

35
Numerical Data Stem and Leaf Plots
  • Stem Leaf
  • 20 1 2 2 5 6
  • 21 0 1 2
  • 22 2 3 8
  • 23
  • 24 0 2
  • 24 0 represents 240

36
Numerical Data Describing a distribution
  • Shape
  • Generally one of three types
  • Symmetric
  • Positively Skewed
  • Negatively Skewed

37
Numerical Data Shape Symmetric
  • Symmetric (same shape either
  • side of the centre)

38
Numerical Data Shape Positively Skewed
  • Positively skewed tails off to the right

39
Numerical Data Shape Negatively
Skewed
  • Negatively skewed tails off to the left

40
Centre
  • The centre as measured by the Median is the value
    which has the same number of scores above as
    below.
  • The centre as measured by the Mean is the value
    which is equal to the sum of the data divided by
    n
  • The centre as measured by the Mode is the value
    which has the highest frequency

41
Spread
  • The maximum and minimum values should be used to
    calculate the range.
  • Range Maximum Value Minimum Value

42
Outliers
  • Outliers are extreme values well away from the
    majority of the data

Outlier
43
Which Graph??
TYPE OF DATA GRAPH WHEN TO USE
CATEGORICAL Bar Chart
Segmented Bar Chart Not too many Categories Max 4-5
NUMERICAL Histogram Med to Large
Stem Plot Small to Medium
Dot Plot Only small data sets

Good luck with your holiday homework
  • It is a good idea to do this before school
    finishes so if you get stuck you can ask us.
