Aims
Study
The following mathematical concepts:
1. Data is a collection of facts and figures that
can be in numerical or nonnumerical form.
2. Data collection refers to the systematic
process of gathering, measuring, and recording
data. This may be done through surveys,
interviews, and observations.
Aims
3. A table is an arrangement of data, typically in
rows and columns, that
summarizes it in easy-to-understand format.
4. Line graph is used to display data that shows
change over time as a series of data points
connected by straight line segments.
Aims
Steps in presenting data in tabular form and single
line graph.
In presenting data in tabular form:
1. Determine the needed number of columns and
rows.
2. Label properly the first row of the table
depending on the data collected (You may also
use the first column for this).
3. Include a title that briefly describes that data
presented.
Aims
In presenting data as a single line graph:
1. Draw a vertical scale with tick marks. Label
the tick marks and give the scale a label.
2. Draw a horizontal scale with tick marks.
Label the tick marks and give the scale a
label.
3. Plot a dot in each data value.
4. Connect the dots and give the graph a title.
