The probability density function of a random variable can be either chosen from a group of widely used probability density functions (e.g.: normal, uniform, exponential), based on theoretical arguments, or estimated from the data (if you are observing data generated by a specific density function). More material on density functions can be found by following the links below.
A distribution table would be primarily used in the field of statistics and probability. Collecting and interpreting data is much easier when compiled in this format.
a data table is a table to place your observations
A test using relative errors comparing a frequency table to the expected counts determined using a given probability distribution; the null hypothesis is that the given probability distribution fits the data's distribution.

Draw up a table with several columns, each representing a variable. Each row in the table is an observation, with data stretching across the columns.
The conclusion supported by the data in the table depends on the actual values provided. If the density remains constant for all substances, you can conclude that density is consistent. If the density changes with mass and volume, you can infer a relationship between mass, volume, and density.
It is called 'Experimental Probability'.
This is a binomial probability distribution; n=12, r=2 & P=.05. Read directly from the table probability of 2 is .099 (plugging this data into my calculator gives 0.09879).

To calculate the density of an element from the periodic table, you would need to know the element's atomic mass and atomic volume. The formula for density is mass divided by volume. You can find the atomic mass on the periodic table and calculate the volume using the element's atomic radius or other relevant data.
