Introductory Message
This Self–Learning Module (SLM) is prepared so that you, our dear learners, can continue
your studies and learn while at home. Activities, questions, directions, exercises, and
discussions are carefully stated for you to understand each lesson.
Each SLM is composed of different parts. Each part shall guide you step-by-step as you
discover and understand the lesson prepared for you.
Pre-tests are provided to measure your prior knowledge on lessons in each SLM. This will tell
you if you can proceed on completing this module or if you need to ask your facilitator or your
teacher’s assistance for better understanding of the lesson. At the end of each module, you
need to answer the post-test to self-check your learning. Answer keys are provided for each
activity and test. We trust that you will be honest in using these.
In addition to the material in the main text, notes to the Teacher are also provided to our
facilitators and parents for strategies and reminders on how they can best help you on your
home-based learning.
Please use this module with care. Do not put unnecessary marks on any part of this SLM. Use

           decreasing curve graph.

Categorical data- is a data that is divided into groups or qualitative characteristic.
There is no order to categorical values and variables.

   EXAMPLES: Gender (male and female), Favorite Colors, cellphones, Celebrities,
             brand of soap an etc.

Quantitative data – is a data measured and expressed numerically. It has numerical
meaning and is used in calculations and arithmetic.

    EXAMPLES: weight, temperature, height, annual income, number of hours of
             sleep etc.

  What appropriate graphs to use to represent a given organized data?
      The appropriate statistical graph depends on the type of data collected and the
purpose of collecting the data.

⚫ A pie chart is most appropriate when we want to show the relative size of each
  data set in proportion to the entire data set.
⚫ A bar graph is most appropriate when we want to compare between the data sets,
  and we want to know the exact numerical values.
⚫ A line graph is most appropriate when we want to show trends over period.
⚫ In an ungrouped data, a histogram is most appropriate when we want to know the
  exact values of the frequencies of the data sets and identify the lowest and highest
  frequencies.
⚫ In a grouped data, a histogram is most appropriate when we want to clearly display
  a large set of data and do not need exact the values of the original data.
⚫ An ogive is most appropriate when we want to clearly display the cumulative
  frequencies of data points that are less than and more than the value in a data set.

                                          5
⚫ Pie chart and Bar graph are appropriate to use when you have a categorical data.
⚫ Line graph, Histogram, and Ogive are appropriate to use when you have a
  quantitative data.

EXAMPLE: The table shows the number of students who travel to school using
         different mode of transportation.
 Mode of Transportation           Jeep       Tricycle    Single Motorcycle Walking
 Number of students                320         160              200         120

What appropriate graph to use in this kind of data?
- A bar graph is the appropriate graph for this kind of data.
- But if you want to see the percentage of students travel using different
  transportation, the pie chart can also display this kind of information.
