Explain how reliability, validity and safety have been considered in a first-hand investigation Flashcards
Explain how reliability have been considered in a first-hand investigation
Reliability has been considered in a first-hand investigation if the experiment has been run multiple times and all the results of the repeated experiments are close and have no outliers.
Explain how validity have been considered in a first-hand investigation
Validity has been considered in a first-hand investigation if the correct equipment has been used, only one thing is being measured and one thing being changed and all other variables are being controlled.
Explain how safety have been considered in a first-hand investigation
Safety has been considered in a first-hand investigation if the risk assessment has been done, if all the correct personal protection equipment is being worn and if all risks have been minimised.
The experiment has been run multiple times but not all the results of the repeated experiment are close, and there are outliers. Has Reliability been considered in this investigation?
No, while the experiment has been run multiple times not all the results of the repeated experiment are close and there are outliers. This means that at some point the repeated experiments changed a little bit and the investigation could not be considered reliable.
The experiment has been run multiple times and all the results of the the repeated experiments are close and there are no outliers. Has Reliability been considered in this investigation?
Yes, The experiment has been run multiple times and all the results of the the repeated experiments are close and there are no outliers. This means that reliability has been considered in this investigation.
The experiment has not used the correct equipment and 2 things are being measured, one thing being changed and all other variables are being controlled. Has validity been considered in this investigation?
No, while one thing was being changes and all other variables were being controlled the experiment did not use the correct equipment and 2 things were being measured. This means that the experiment could not be considered valid because there were multiple things being measured and the correct equipment was not used.
The experiment has used the correct equipment and one thing is being measured, one thing being changed and all other variables are being controlled. Has validity been considered in this investigation?
Yes, The experiment has used the correct equipment and one thing is being measured, one thing being changed and all other variables are being controlled. This means that validity has been considered in the investigation.
The experiment has done the risk assessment, however has failed to wear correct personal protection equipment and risks have not been minimised. Has safety been considered in this investigation?
No, the experiment has done the risk assessment, however has failed to wear correct personal protection equipment and risks have not been minimised. This means that the experiment is dangerous to carry out and safety has not been considered in this investigation.
The experiment has done the risk assessment, is wear correct personal protection equipment and risks have been minimised. Has safety been considered in this investigation?
Yes, the experiment has done the risk assessment, is wear correct personal protection equipment and risks have been minimised. This means that the dangers of the experiment have been minimised and safety has been considered in this investigation.
