**8. Data Analysis**

* Process relevant data for meaningful interpretation of experimental
results

* Present data in different types of graphs

* Using
statistics and trend lines

Introduction
(5 mins)

+ Teacher
to ask students how would they analyse their data after collection.

Development
(40 mins)

+ Teachers to highlight the awareness that different research methods requires different approaches of analysis.

+ Teachers to highlight the awareness that different research methods requires different approaches of analysis.

+
Students are given some sample data for analysis. These samples will be similar
to exam questions on data analysis.

+
Students plot different types of graphs:

(a) Histograms
for category data

(b) Curves

(c) Straight
line graphs

+
Teachers to introduce to the students basic statistics:

(a) taking
averages, standard deviation and error bars.

(b) finding
the trend lines

(c) calculate
gradient and y-intercepts for straight line graphs

Conclusion
(5 mins)

+ Teacher remind students that the knowledge learnt in
Physics, Chemistry and Biology are relevant to the ISS data analysis skills.
