Question

Help with bio? Which are independent variables and dependent variables? Will fan and medal. (:

Answer 1

This is what I have... I know I'm wrong tho lol

Independent Variables: water, coca cola, and vegetable oil.
Dependent Variables: nickel, syringe.

Answer 2

uhm so I need more info

Answer 3

but let me give you an example.

Answer 4

What I'm testing:

Using 3 different substances, water, coca cola, and vegetable oil, if I were to drop the liquids onto a nickel, how many droplets could be spilled onto the nickel before the liquid spilled off of it?

Answer 5

What do you think it means for something to "depend" on something else?

Answer 6

For it to stay the same. @skullpatrol

Answer 7

eg:
YO MAMMA IS SO FAT, she eats 8000 calories a day. Her weight goes up every day because she doesn't do any exercise.

So how much your mother weighs depends on how much she eats, but how much she eats is an independent choice.

Answer 8

It doesn't stay the same. It "follows" it @kmullis6

Answer 9

(and the amount of exercise she does but disregard that)

Answer 10

Oh ok. Had them mixed up /:

Answer 11

@FibonacciChick666 Ok, that helps. (:

Answer 12

does the amount of droplets depend on anything? Can anything modify it?

Answer 13

Depends is a relationship between two or more things.

Answer 14

and you have to make it funny when possible :)

Answer 15

It depends on how even the surface is? Does that count?

Answer 16

You got the idea :-)

Answer 17

So the dependent variables are the water, coca cola, and vegetable oil?

Answer 18

uhm well how about this more practical example.
I am testing a cornstarch and water solution to see how high I need to drop a 5g, a 10g, and a 50 weight and have it hit a solid surface.
My independent variable would be the weight of the object. The dependent would be my final height.

Answer 19

Those @kmullis6 would be the 3 categories of liquids you are testing.

Answer 20

Because my experiment has nothing to do with changing the weight, that is why it is independent. It stands alone. I don't affect it.

Because \(\color{red}{the ~height~ will~ change ~based ~on ~the~ weight}\) it is my dependent variable.

Answer 21

@FibonacciChick666 ok i think i get it

Answer 22

so what is the difference between your liquids?

Answer 23

what is different about them that you are testing?

Answer 24

The thickness? Probably not the right word to describe them, but... :P @FibonacciChick666

Answer 25

i think I'd go with viscosity maybe, but anyways what do you effect? what is changed in the experiment. what depends on another event? (please stop tagging me each time btw, it's not really necessary)

Answer 26

Haha sorry :P

Answer 27

I'm used to people leaving while helping me, just a habit.

Answer 28

i do, but I still get a notification for the question without being tagged haha

Answer 29

The amount of droplets?

Answer 30

right and what does that depend on?

Answer 31

The surface, how fast and slow I'm dropping them?

Answer 32

uhm, yes, but not really. we assume they are all dropped at the same rate and on the same surface

Answer 33

and in the same location

Answer 34

yea true. sorry ive always been terrible at doing this for some reason.

Answer 35

NEVER SAY THAT!!!! (HUGE PET PEEVE) Never say that you are bad at something. If you do, you will forever and always be bad at it. If you must have negative thoughts, say something like "I just haven't practiced enough yet" or " I just need to learn more to be better".

Answer 36

lol i know i shouldnt

Answer 37

Well said @FibonacciChick666 ... It is much more productive to search for the reason why you don't understand something @kmullis6

Answer 38

Remember good students learn from their mistakes as well as their successes :-)

Answer 39

I didn't mean it the way I said it haha it came out wrong. I've always had a hard time with this was my only point. And that I'm a sophomore and I still get confused. I've tried really hard on these things so I can understand.

Answer 40

Sometimes, in math, you have to "work smart" and not just hard.

Answer 41

This isn't math tho, it's bio. Same thing tho, I guess.

Answer 42

Spend your time wisely trying to find what you don't understand and most importantly WHY you don't understand it.

Answer 43

^^very very true

Answer 44

So can you help me on which is the dependent variable(s)? I can't think of anything else. /:
