3. What is STATISTICS?
STATISTICS is a branch of
mathematics that deals with
collecting, organizing, presenting,
analyzing, and interpreting data
to come up with a useful and
meaningful information.

4. Branch of STATISTICS
Descriptive Statistics is used to
describe and summarize collected
sample data. These data can be
shown using graphical and tabular
representations. Types of
descriptive statistics includes
frequency distribution, central
tendency, and variability.

5. Branch of STATISTICS
Inferential Statistics is used to
analyze sample data which leads to
inferences, generalization,
conclusion, and decision of the
population data. Hypothesis testing
is commonly being used as
statistical instrument.

6. MEASURE OF POSITION
Measure of position includes dividing
the data into four parts, ten parts,
and hundred parts of equal sizes. The
corresponding partition values are
called quartile, decile, and
percentiles. These values can be
determined in the same way as the
median. Only the location is the main
difference.

7. MEASURE OF POSITION
Consider the midpoint of two
numbers a and b on the number
line is
𝑎+𝑏

𝑎+𝑏
