Chi-Squared
What is the null hypothesis?
The average of all the data
What is mean?
a quantity calculated to indicate the extent of deviation for a group as a whole
What is standard deviation
Measure of temperature in which 0 is the lowest point on the scale.
What is Kelvin?
What is the average rate of flow if at t = 0s there are 30 gallons in a pool and at t = 5s there are 0 gallons in the pool.
What is -6 gallons/second?
The hypothesis that states that there exists a significant difference between two specified populations
What is the alternate hypothesis?
The data point that shows up the most in a set
A function that describes the distribution of data as bell shaped
What is a normal distribution?
The pressure exerted from the presence of concentrated particles in a solute.
What is solute potential?
(1,4,6,7,14,15,17,23,78,101)
What is 100?
What is the P-Value?
The difference between the highest and lowest values in a set
What is range?
The number of standard deviations from the mean?
What is z-score?
The measure of the relative tendency of water to move from one area to another, and is commonly represented by the Greek letter Ψ
What is water potential?
Two cells have a surface area to volume ratio of 3:1 and 4:3. which one has a better ratio?
What is the cell with a ratio of 3:1?
This is the number of categories minus one
What are degrees of freedom?
The middle term of a set organized by magnitude. If there are an even number of terms, it is the average of the 2 middle terms.
What is median?
A situation in which two events both may not be true
What is mutually exclusive?
If the pressure potential is 0 then this equals the solute potential
What is water potential?
The percent of the bell curve is within 1 standard deviation of the mean
What is 68%?
The values that are calculated by multiplying the total number in the sample by the probability of occurrence for that variable.
What is the expected value?
What is the average of this data set?
(1,2,3,4,5,6,7,8,9,10)
What is 5.5?
The approximate standard deviation of a statistical sample population
Used to determine whether the sample is an appropriate for the population
What is standard error?
-iCRT
What is the formula for solute potential?
the surface area to volume for a cubic cell that has a side length of 3
what is 54:27 or 2:1?
