Question

The density of a sample of metal is calculated using these three different sets of data: 0.6 g/mL, 2.4 g/mL, and 1.8 g/mL. If the true density of the metal is 1.2 g/mL, what can be said about these calculated density values?

The set is both accurate and precise.

The set is accurate but not precise.

The set is precise but not accurate.

The set is neither accurate nor precise.

Answer 1

mm, accuracy - how close the measurement to the true value
precision - did you get the same results ?

so i believe the answer is neither.

Answer 2

Yes thats what i got thank you! i just wanted someone elses opinion.

Answer 3

yw :)

Answer 4

A scientist in London and a scientist in California both conducted independent investigations that produced similar results.

What does this mean about the data that was collected?

The findings are considered stronger and more reliable because they were repeated.

The scientists will have to compete for the credit for this discovery.

The scientific community will vote on the name of any resulting theory, in order to keep things fair.

The findings are automatically promoted to a law because they were proven by two different scientists.

Answer 5

I'll go with the first one.

Answer 6

Do you think that creativity can contribute to the development of a scientific experiment or investigation? Give an example to support your answer.

Answer 7

2.What features make a question scientific, and why are some questions beyond the boundaries of scientific investigation?

Be sure to include examples to support your answer

Answer 8

please help me!!

Answer 9

Creativity can and surely does contribute to the development of a scientific experiment or investigation. Don't you think Newton was creative in thinking about the universal gravitational law when he merely saw an apple falling ? Creativity leads to innovations and then more research and then discovery.

Answer 10

A question is scientific when it can be answered by using logic and scientific information we have currently, or if there is scope for it to be answered in future because of further development in technology / theories. Scientific questions are based on facts that are observed, just like that of magnet attracting bits of iron, etc.

Few questions like existence of God / existence of demons are beyond science as they are not based on any observation.
