An example of bias: Taking a survey about who likes music and who does not, while standing by the door of a CD store. This is biased because if you are by a music store, most of the people there that you survey will like music. The results will not be completely random, so they will not accurately show what that percentage of the population really thinks about music.

Why can't you just add the exponents when the bases aren't the same?
It just doesn't give the correct result. Try some sample numbers, to verify that it doesn't provide the correct result.
Would taking measurements of the same object several times and then averaging them give a more accurate measurement?
Generally, yes, because the averaging removes the effects of random errors in the measurements. However if your measurement technique has biases, these will not be removed through averaging and the averaged result will be biased.
What is the Sample space for 4?
In order to determine the sample space, an actual description of the problem is needed. A number doesn't give the required information.
How can you calculate BOD Mathmaticly?
The Biochemical Oxygen Demand (BOD) of a sample is the amount of dissolved oxygen required by aerobic microorganisms to breakdown organic matter in the sample.The test is simple:Measure the Dissolved Oxygen content of the sample (a)Place in a sealed darkened bottleIncubate for 5 days at 20'CMeasure the Dissolved Oxygen content of the incubated sample (b)Generally you're using this test to analyse contaminated water, so you'll want to dilute it first - it may be that aren't enough aerobic microorganisms present to give you a measurable result, in which case you'll need to inoculate the sample with a suitable culture.The BOD of the sample = a - bBOD is expressed in mg O2/L of sample.Extra CreditGenerally you're using this test to analyse contaminated water, so you'll want to dilute it first - it may be that aren't enough aerobic microorganisms present to give you a measurable result, in which case you'll need to inoculate the sample with a suitable culture.The BOD of a diluted innoculated sample = ((a - b) - BOD of inoculated culture) * dilution factor

Why did the literary digest poll fail?
The literary digest only polled its readers and its readers were not a random sample. Only people who liked to read and had money to spend on books took the literary digest. Thus their poll was biased and did not give an accurate result.
What indicators do the experimental result give regarding the purity of the sample?
After a detailed chemical analysis the purity is correctly evaluated.
If Biuret and Millon's test give positive result what is the conclusion?
If both Biuret and Millon's tests give a positive result, it suggests the presence of proteins in the sample. Biuret test is specifically for proteins containing peptide bonds, while Millon's test is used for identifying proteins with tyrosine residues. The positive results from both tests provide strong evidence for the presence of proteins in the sample.
Why can't you just add the exponents when the bases aren't the same?
It just doesn't give the correct result. Try some sample numbers, to verify that it doesn't provide the correct result.
Will waxes give a positive result toward acrolein test?
Yes, waxes can give a positive result in an acrolein test because acrolein is a byproduct of the thermal degradation of some waxes, leading to its presence in the sample being tested.
Can you give me a sentence for the word bias?
Bob: "You have a biased opinion." Jim: "Your face is biased!!" Bob: "That is quite absurd!" Jim: "Go suck your biased motha fu***s face!"
Does a colony count really give a total count of microorganisms per unit sample of the original material?
A colony count provides an estimate of the number of viable microorganisms that are able to grow under the specific conditions used for culturing. It does not give a total count of all microorganisms present in the sample, as some may not be culturable or may not grow under the conditions used.
What will be the result in the recrystallization of an impure unknown sample?
During recrystallization, the impurities in the unknown sample will be left behind as the pure compound crystallizes out of the solution. The impurities will either remain dissolved or form separate crystals, leading to a purification of the unknown sample.
Mr. Golden surveyed people leaving a fitness center to determine American attitudes toward exercise. Give the best explanation for why the results of this survey might NOT be valid?
The survey is biased because the sample consisted only of people who already exercise.
