Statistics is a branch of applied mathematics focused on data collection, analysis, and interpretation, playing a crucial role in various fields such as education, science, and government. It helps consumers critically analyze information, avoiding misleading representations, while assisting manufacturers in quality control and decision making. Understanding statistics enables informed citizenship and effective problem-solving by applying statistical methods to gather and analyze data.

1. REAL-LIFE PROBLEMS
THAT CAN BE SOLVED
BY STATISTICS

2. STATISTICS
is a branch of Applied Mathematics
specializing in procedures for
collecting, organizing, presenting,
analyzing, and interpreting data
from observations.

3. USES OF STATISTICS
In Education, it is frequently used
to describe test results.
In Science, the data resulting from
experiments must be collected and
analyzed.
Manufacturers can provide better
products at reasonable costs
through the use of statistical quality
control techniques.

4. USES OF STATISTICS
In government, many kinds of
statistical data are collected all
the time.
A knowledge of statistics can
help you become more critical in
your analysis of information;
hence, you will not be misled by
manufactured polls, graphs, and

5. A statistical question is one that
can be answered by collecting
data and where the answer can
vary.

6. TYPES OF DATA:
Numerical data set are those in
numerical form which are either
continuous or discrete.
Discrete data are those that can
be counted in a finitely while
continuous data are
measurements that can take any
value from an infinite range.

7. TYPES OF DATA:
Categorical data take nonnumerical
values, such as colors, information
or questions that are answerable by
YES or NO, labels, etc.

8. IMPORTANCE OF STATISTICS
The study of statistics is
important because society
frequently organizes and
expresses data numerically.
Statistics shapes our lives and
influences our decisions.
Statistics is often used by media
experts to inform or mislead
consumers.

9. IMPORTANCE OF STATISTICS
It is important to process statistical
information effectively to function
as knowledgeable citizens in
society.
Problems and questions that can be
solved using statistics should be
clear, specific, realistic, manageable
to conduct data collection and
allows statistical analysis.
