What is Qualitative Data?

flies
i did an experiment, “Does the weight affect the distance traveled (of a match rocket)?” [a match rocket is a match, of course, wrapped with Al foil at its head and placed on a bent paper clip used as a stand...and then light it with a lighter and then batbingbatboom.. it flies some centimeters...] well i got the results weight does affect the distance traveled.. and the lighter match flew further. (40cm to 20cm.) so i dont understand what to but under the results as qualitative data…PLEASE someone help, i’m dying to know..due tomorrow!!!!!!! or the next 8 hours and 30mins!! more like 7hrs, cause i’ll be at school..but i want to sleep soon..so yeah!! thankssss!

Qualitative data is the kind you got. You can state that when the match was made lighter it went farther, but you can’t state the exact weight change, whether the aluminum wrap was exactly the same for both conditions,or the effect of any other variables.
Quantitative data is data with firm numbers indicated.

quantititative data is numerical data; qualitative data is data that describes the qualities of the thing being described.
In your experiment I would guess that under qualitative you would put the weight of the match and length it flew. Qualitative data would be “wrapped with foil” or “not wrapped with foil”.
I THINK this is correct. For sure the numerical stuff is quantitative. I believe the description (flufflier, wrapped vs unwrapped etc) is qualitative.
For extra credit, do a graph and show HOW the weight affects distance. The teacher will be impressed enough that if you goof on ‘qualitative’ they won’t mind.
