SE + WP

Question 1

SE definition

Answer 1

SE–range of WHERE MEAN SHOULD FALL. standard error–tells us how accurate estimate of the mean is. the smaller the standard error, the more accurate our estimate is. Few samples = larger standard error. many samples= smaller. 60, 70, 80, vs 60, 65, 70, 75, 80

Question 2

SD definition

Answer 2

how spread out the numbers are that defined the mean.. 68, 69, 70 vs 59, 69, 79

Question 3

water potential info

Answer 3

measure of how likely water is to move from location A (outside cell) to location B (inside). moves from greater to lesser.

Question 4

water potential is greater in location A if…

Answer 4

water in location A has greater potential to move

Question 5

water potential formula

Answer 5

solute potential + pressure potential

Question 6

water potential of pure water

Answer 6

0

Question 7

solute potential

Answer 7

-iCRT

Question 8

i

Answer 8

i=ionization constant/how many ions that solute forms in water

Question 9

C

Answer 9

molar concentration

Question 10

R

Answer 10

pressure constant (R = 0.0831 liter
bars/mole K)

Question 11

T

Answer 11

temperature in Kelvin (ºC + 273)
