Lecture 4: Designing an Experiment

Question 1

Research is the process one goes about to finding the answer to a particular question

Research can be (types)?

Answer 1

Hypothesis driven or Exploratory

Question 2

Hypothesis driven research involves

Answer 2

Generating a hypothesis, designing an experiment that tests this hypothesis and then accepting or rejecting the hypothesis based on the results – observe, hypothesise, go about the experiment and revise the hypothesis/design new experiments

Question 3

Exploratory research is the

Answer 3

systematic analysis and observation of samples with the goal of increasing knowledge and potentially generating a hypothesis based on the new information

Question 4

Hypothesis driven experiments have to test the ____ and will usually require

Answer 4

Hypothesis

Will usually require:

• Positive or negative controls,
• Need to be able to be repeated,
• Need accurate methods of collecting data
• The data gathered should have a good method of presentation and display.

Question 5

The result of hypothesis driven research will be used to

Answer 5

assess the hypothesis as well as if new questions have been raised

The process of revising hypotheses is often a continuous process as it is constantly being revised

Question 6

An example of exploratory research is drug screens

Answer 6

They aim to identify new chemicals with specific effects.

These screens can look for morphological, therapeutic or pathway directed effects

Question 7

In the lab, there is often a _________ of ______of research used to answer particular question

Answer 7

In the lab, there is often a combination of both types of research used to answer particular question. The finding of exploratory research can kickstart hypothesis-based research.
