In this tutorial, we
shall:

1. Estimate the dimension
and distance within a school.

2. Estimate the objects.

3. Estimate the
statistics of people, e.g., Height.

4. Solve problems in
quantitative reasoning in estimation.

**Objectives**

By the end of the lesson,
you should be able to:

i. Define estimation and
other keywords.

ii. Round off numbers to
a required significant figure and to the nearest 10, 100, tens, etc.

iii. Use rounded values
to estimate the outcome of values.

iv. Estimate the
dimension and distance within places.

v. Estimate the
statistics of people, e.g., Height.

vi. Solve problems on
quantitative reasoning in estimation.

**Keywords**

1.

**Estimate**
This simply means to find
a rough or an approximate value.

2.

**False accuracy**
This is when a value is
more accurate than it should be.

3.

**Approximation**
This is the process of
using rounded values when presenting numerical data and making rough
calculations.

4.

**Significant figure(s)**
Counted from the first
non-zero digit at the left of the number.

5.

**Rounding off**
This simply means to find
an approximated value for a number.
