Hi, I hope you can help.
I collected my samples on the street by just asking passers by to fill in my questionnaire. I moved to 5 different locations within the city and spent 3 hours each visit 3 times a week for one month.
Is this random sampling? Or it it sill convenience sampling? Can...
Hi.
I was hoping you guys could help me for my university dissertation project. It's basically a questionnaire about climate change, it shouldn't take any longer than 10 minutes (or quicker) and it would be really helping me. If you have any comments about it please feel free to message me on...
hi, i was just wandering what colour you see best in a why?, i mean if a room was to be flooded in red blue or green what would be the best for the resolving power of the eye.
thank you very much, alex
Hmmm Solar nutrinos... We have not currently covered that in our sylabus currently! Maybe i should stick to something i already know about!
I was thinking about doing my project as a kind of time line i.e starting off with Newton thinking it as waves, then einstein with the photoelectric effect...
thanks guys, well all we've been asked to do is research somehting. Its not a practical experiment, we've just gota use books interweb ect to find out about something.
Any of you guys got any other goos ideas??
Would this be a good idea for a research project, i.e as it has controversey in it, photoelectric effect verses Youngs double slit.
im doing A-level, and this is a piece of coursework.
thank you!
every subect seem to be different! which kind of graph and a lot what axis do i plot, if i was to do plot resolution against lux! plus anyone kno the proper way to do this in excell. thanks
ive done a test were, i get someone to try and distinguish to lines that are 0.25mm apart from varying distances. then I am going to do some kind of calculation to tell me somthing (hopefully)
and i have done this experiement in different light levels, controlling the lux. and i have...
hi, I've just done an experinemt to try and show the resolution of the human eye in different light levels.
i did it by putting a 0.25mm apart slits in a tube then, behind it had an adjustbable light, then i moved the slit further back, and asked them to say if they could see the two slits...
