### Lesson 21

__8. Data Analysis__

__* Process relevant data for meaningful interpretation of experimental results__

__* Present data in different types of graphs__

__* Using statistics and trend lines__
Strategies

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.
