What is a hypothesis?

• an untestable statement

• a possible explanation for an observed phenomenon

• an experiment

• whatever the lecturer tells you is the truth

What is the first step in the Scientific Method?

• publication

• background research

• observation

• hypothesis

These are the 6 steps of the Scientific Method

formulate a hypothesis;

publication; research;

analysis and conclusion; observe and question;

test hypothesis

Can you type them in the correct order ??

In the introduction section of a scientific article, the authors ...

(tick all that apply)

• describe the statistic tools they used

• introduce the observation and the question they want to address

• detail the results of the experiments they performed for this study

• relate the research performed by preceding studies that also addressed this question

• formulate the hypothesis

How do you make a conclusion?

• you perform several different tests until you obtain the results you are looking for

• you look at your hypotheses and choose which one you prefer

• you compare the data from your experimental results to the prediction they tested

• you look at previous research and calculate what the results should be

A dependent variable ...

• is what you change in the experiment, and is what affects the independent variable

• is what you measure in the experiment and what is affected during the experiment

• is what remains constant during the experiment

• is what you cannot measure in the experiment

When collecting data you have to ...

• check if you have reached a significant result

• record everything in a lab book

• make sure you have the same number of female and male participants

• make sure you know everything about each subject

What is a protocol?

• a book recording everything you have done during an experiment

• a license from the Home Office allowing you to do experiments

• a set of rules that define what is right and what is wrong in your experiment

• a set of procedures that you must follow

There is a big noise in the recording. This noise has a frequency of 50 Hz. How can we get rid of it?

• a band pass filter around 50 Hz

• a notch filter at

  50 Hz

• a low pass filter at 50 Hz

• a high pass filter at 50 Hz

A sensor is a device that detects and responds to some type of input from the physical environment

• TRUE

• FALSE
