How do you get the specific gravity of a mineral?
Fill a beaker with water, and weigh it. Weigh a sample of the mineral. That's the mass of the mineral. Put the sample in the beaker and weigh that. The weight of the water-filled beaker plus the weight of the mineral sample will be greater than the weight of the beaker with mineral sample and water. The difference is the weight of the displaced water, in grams. The volume of the mineral sample, in cubic centimeters is equal to the weight of the displaced water, in grams. Calculate the specific gravity of the mineral by dividing the weight of the mineral sample by the volume of the mineral sample. Example: your beaker weighs 40 grams. Filled with water, it's 1040 grams. The sample of mineral weighs 160 grams. The beaker with the sample of mineral and water weighs 1179.7 grams. The mineral, and the beaker with water would have a combined weight of 1200 grams, but the beaker with mineral and water weighs 20.3 grams less than that, so the mineral sample is displacing 20.3 cubic centimeters of water. Given a mass of 160 grams and a volume of 2.03 CC, the specific gravity would be found by dividing 160 by 20.3. It's 7.85. (Which happens to be the specific gravity of some iron.)
What is the mineral property defied by Density of the mineral sample divided by the density of water?
Specific gravity.
What type is Sample B on Mineral Identification on Gizmo's?
feldspar
What is the color of the mark made when a mineral sample is rubbed on a harder surface?
The mark is called a streak and the color depends on what mineral you are testing.
Which mineral sample would experience the most abrasion?
Galena - cause of the hardness of only 2.5
What are mineral samples?
its a sample of a mineral!
What is not dependent on the size of a sample?
In general the mean of a truly random sample is not dependent on the size of a sample. By inference, then, so is the variance and the standard deviation.
The purpose of statistical inference is to provide information about the?
The purpose of statistical inference is to obtain information about a population form information contained in a sample.
What is the meaning of the term statistical inference?
Statistical inference is a conclusion about the value of a population parameter based on information from the corresponding sample statistic and the associated probability distribution.

Scientific definition of inference?
Actually inference is based upon statistical evaluation of data. Inference is a generalization made about a defined "population" from data obtained from one or more "samples". Each member of the population must have an equal chance of being included into a sample. An example would be when a number of people from a particular state are asked who they would vote for. The "inference" would be a generalization that the state favors a particular candidate 55% TO 45%. The validity of the inference would depend upon sample size and how true the sampling was to giving every member of the sampled population (the entire state) an equal chance to be included in the sample.
The process of using sample statistics to draw conclusions about true population parameters?
statistical inference

What is a logical explanation of an observation drawn from prior knowledge or experience?
No. A conclusion is based on an experimental result, which attempts to explain how the prior information applies to a given hypothesis.
