Best ResponseYou've already chosen the best response.0Which one do you think it is?

Best ResponseYou've already chosen the best response.0What was always the same in experiment even when another variable changed.

Best ResponseYou've already chosen the best response.0I'm thinking C, I'm not really good with science.

Best ResponseYou've already chosen the best response.1The control something that isn't changed

Best ResponseYou've already chosen the best response.1they're testing the effects of cleaner on the growth of mildew. so think.. they use two cleaners, and they want to test the effectiveness of each, how would they know how effective they are if they didn't have a third group where no clearer is used?

Best ResponseYou've already chosen the best response.1so you need to think about what was kept constant in this experiment in terms of the control @sunflow1

Best ResponseYou've already chosen the best response.0Okay, so I think Brand X was kept constant because it was good for 3 days.

Best ResponseYou've already chosen the best response.1hmm. if i'm correct the the numbers correspond to the area as in the growth of mildew so for brand X you can see that for three days the mildew is virtually nonexistent it's zero. but for brand Y there are values for three of the days so which one would be more effective?

Best ResponseYou've already chosen the best response.0Uhh Barnd Y... @Photon336

Best ResponseYou've already chosen the best response.1@sunflow1 think of it this way. the purpose of this experiment is that you want to see which brand is more effective at killing mildew. the brand that's more effective at killing mildew will be the one that has the lowest area in growth mm follow?

Best ResponseYou've already chosen the best response.0Yes. Sorry if I'm frustrating you.

Best ResponseYou've already chosen the best response.1no you're not; it's probably that I'm not explaining it clear enough

Photon336

Best ResponseYou've already chosen the best response.1so we can see that BRAND X is the better cleaner than BRAND Y because the area in mm for the mildew for brand X is much less

Best ResponseYou've already chosen the best response.1(note they said something else): " they made sure that they did the experiment on the same tiles"

Best ResponseYou've already chosen the best response.1why is this important?

anonymous
 one year ago
Best ResponseYou've already chosen the best response.0It's Important because they want to make sure they are testing it right...im not sure.

Photon336

Best ResponseYou've already chosen the best response.1yeah.. that's correct ( because if they used different tiles) then the mold might grow faster or slower depending on the tile and they want to make sure that they are testing it correctly/

Best ResponseYou've already chosen the best response.1so would that be our control?

anonymous

Best ResponseYou've already chosen the best response.0Wait is a control a factor in an experiment that remains the same

anonymous
 one year ago
Best ResponseYou've already chosen the best response.0so that means it would be C

Photon336

Best ResponseYou've already chosen the best response.1yeah that makes most sense to me the four days wouldn't be controls and the two sprays would be controls either so those are out.

Best ResponseYou've already chosen the best response.0awesome. Can you help with the last two? @Photon336

Best ResponseYou've already chosen the best response.1let me ask you this question: what are we manipulating here in this experiment? @sunflow1

anonymous
 one year ago
Best ResponseYou've already chosen the best response.0The tiles independent variable the one factor that a scientist changes during an experiment; also called manipulated variable

Photon336

Best ResponseYou've already chosen the best response.1I believe that it's the type of cleaner

Photon336
 one year ago
Best ResponseYou've already chosen the best response.1because they used the same tiles remember?

anonymous

Best ResponseYou've already chosen the best response.0yes, I kind of confused. :(

Photon336

Best ResponseYou've already chosen the best response.1@sunflow1 what changes as a result of using a different cleaner?

Photon336
 one year ago
Best ResponseYou've already chosen the best response.1it's the size of the mildew

anonymous

Best ResponseYou've already chosen the best response.0Oh right, so it would be B bc the midew changes

Photon336

Best ResponseYou've already chosen the best response.1so the size of the mildew depends on the cleanser used does that make sense and why?

anonymous
 one year ago
Best ResponseYou've already chosen the best response.0Yes, because if the mildew grows and grows that means that type of cleanser isn't the kind you want to get. If its less mildew than its the type you would want, am i right?

Photon336

Best ResponseYou've already chosen the best response.1so what would be the independent variable and what responds to it ( the dependent variable?)

anonymous
 one year ago
Best ResponseYou've already chosen the best response.0The independent variable would be B?

Photon336
 one year ago
Best ResponseYou've already chosen the best response.1independent variable = type of cleanser used dependent variable = growth of the mildew

Photon336

Best ResponseYou've already chosen the best response.1does this make sense to you? if not let me know

anonymous

Best ResponseYou've already chosen the best response.0Ok thank you so much

Photon336
 one year ago
Best ResponseYou've already chosen the best response.1yeah last thing: Independent variable is what causes the other variable to change dependent variable. in our case the type of cleanser is what influences the growth of the mildew

Best ResponseYou've already chosen the best response.1once you've identified that relationship you can't get it wrong ever because that's really what it is at the core of it all.
