How Data is Determined
Determining Data
This and That
100
This type of data involves using numbers.
What is quantitative?
100
This is the tube through which one looks into the microscope.
What is the eyepiece?
100
This is the branch of mathematics that deals with the collection, classification, analysis, and interpretation of data.
What is statistics?
100
3, 4, 7, 8, 8, 9 This is the mode in the data set.
What is 8?
100
True/ False What is scientists should always change there data to match there results?
False scientists never change there data.
200
This type of data us written in the form of words, drawings, or other non-numerical form.
What is qualitative?
200
This is the vertical section at the back which is used to help carry the microscope.
What is the neck or arm?
200
This is the average of the numbers in a data set.
What is the mean?
200
3, 4, 6, 7, 8, 9, 11 This is the median in the data set.
What is 7?
200
Scientists must keep accurate records. Explain why it is important to state the measurement unit you use?
What is so that communication is clear to other scientists?
300
Name a question that cannot be answered by a scientific investigation.
What is a question about God or something that can be looked up in a book?
300
This usually contains the three lenses or objectives.
What is the nosepiece?
300
This is the value that occurs most often in a data set.
What is the mode?
300
3, 5, 7 This is the mean of the data set.
What is 5?
300
Using a larger sample size is better than using a small one. Explain why.
Predictions are usually more accurate with a larger sample size.
400
This is the reason scientists often work in teams.
What is they get more accomplished and they bring different strengths to the team?
400
These are the knobs used to focus.
What are fine and coarse knobs?
400
This is the middle number in a sequence of numbers.
What is the median?
400
1, 2, 5, 7, 9 This is the range of the data set.
What is 8?
400
This is what scientists must have before they change their minds.
What is evidence?
500
These are the three types of scientific investigations.
What are survey, study, experiment?
500
This is the part that many microscopes have a device just under the stage that can be opened or closed to adjust the light that is let in.
What is the diaphragm?
500
This is the difference between the largest and smallest values in a data set.
What is the range?
500
This is the reason why some scientists plot there data on a number line.
What is to see what the extremes are, what the trends are, what the gaps are?
