Activity 1.2: Think and Analyze!
The actual value of the Density of
gold is 19.32g/cm3.
The students performed the
experiment and obtained the
following data:
Trial 1
19.25g/cm3
Trial 2
19.41g/cm3
Trial 3
19.30g/cm3
Average = 19.32g/cm3
Is it precise?
No
Why?
The measurements are’nt close
to each other.
Is it accurate?
No, either
Why?
The measurements aren’t close to the
specific value
A group of students worked in separate teams
to measure the length of an object. Here are
their data:
Team1 5.80cm Team 5.90
4

Does is show accuracy? No
Why? They are not close to the specific length.
Are the data precise?
No, either
Why? They are not close to each other.
The actual value of the speed of light
is 3x108m/s.
The actual value of the index of
refraction of diamond is 2.42
The students performed the
experiment and obtained the
following data:
Trial 1
1.5 x108m/s
Trial 2
6.3 x108m/s
Trial 3
9.2 x108m/s
The students performed the
experiment and obtained the following
data:
Trial 1
6.1
Trial 2
6.2
Trial 3
6.0
Average = 5.67 x108m/s
Average = 6.1
Is it precise?
Is it precise?
No
Yes
Why? The data are not even close to
each other.
Why? The data are close to each other.
Is it accurate?
No
Why?
The data are not even vlose to the
average.
Is it accurate?
Why?
Yes
They are also close to the average value.
CHECKING YOUR UNDERSTANDING
Accuracy is
the closeness
of the
measurements to a
standard
value.

Both Accuracy
and Precision
are used in
context of
measurement.
Also, both show
the closeness of
a measurement
to an actual
value.
Precision
refers to the
closeness of
two or more
measurements to
each other.
Precision
