Learning Objectives

Indicator: B8.4.1.1.2 - Select and justify a method to collect data (quantitative and qualitative) to answer a given question.

By the end of the lesson, learners can:

Identify quantitative and qualitative data collection methods (survey, observation, experiment, interview) and match each to an appropriate research question.
Justify their choice of data collection method by explaining why it is the most suitable for a given question, considering factors such as accuracy, cost, time, and the nature of the data needed.
Design a simple data collection form or questionnaire to gather data for a chosen study.
Evaluate the strengths and limitations of different data collection methods in answering specific questions.
Pose their own research question suitable for investigation and select the appropriate method to collect data to answer it.

Exemplars (from the NaCCA curriculum)

E.g. 1- To study how eating cream crackers affects one's output of work (productivity), identify which method can be used to gather the facts for each of the following situations. (i.e. refer to methods stated in
E.g. 2 of B7.4.1.1.1)
i. Will eating twice a person's normal number of cream crackers increase their productivity?
ii. Are people who eat more cream crackers more productive?
iii. Does a group of students study better when cream crackers are present or absent?
E.g. 2 -Select any study to be undertaken and design an appropriate form to be used in collecting data.
