A set of data is typically a set of numerical values. From this set you can calculate various other numbers which have meaning, like the average and range. These are callled statistics.
If it can be assumed that this set of data is taken from a large population (a sample), then we can make statement of probability regarding the population. For instance, the mean of the population is between x and y with a probability of 50%, based on the sample and other assumptlions.
I've included a couple of links that should help. If I failed to anwer your question, please clarify what you mean by "uncertainty of the values."
No, they need not.
The first thing to consider is whether the data are random.
It would be a group of cells in Excel that have values in them. These can then be identified for use in creating charts in Excel. Different charts need data series for them to show.
-- Find the volume of a sphere with radius = 1.56 -- Find the volume of a sphere with radius = 1.61 -- The uncertainty is the difference between the bigger result and the smaller one. -- For the percent uncertainty, find out what percent that difference is of the (r = 1.56) volume. (Divide the difference of the two volumes by the volume you get with r=1.56 . Multiply the result of the division by 100, and you have the percent of uncertainty.) (Just knocking it out quickly on our calculator, we get about 9.93% uncertainty. This may or may not be correct, and you should not depend on it. But if you get the same answer, then we're probably both right.) Here's an important tool that you'll need to do this job: Volume of a sphere = 4/3 (pi) (radius)3
To evaluate means to find the value. Substitute the values of the variables and calculate the value. [You may need to solve for the values of the variables first.]
Uncertainty can be measured using statistical tools such as standard deviation or variance. These calculations help quantify the dispersion of data points around the mean, providing a measure of how spread out or uncertain the data is. Additionally, uncertainty can be assessed through qualitative methods like scenario analysis or expert judgment.
The greater the sampling error the greater the uncertainty about the results and therefore the more careful you need to be in the interpretation.
No, they need not.
You don't know how much need there is out there for your service or product.
The first thing to consider is whether the data are random.
Un-normalization of data will return the actual values of outcome, which is real value. Because we scale the data in normalization process.
After you collect data, you need to analyze them. Perhaps you need to find the average of your data. Calculators are handy tools to help you do calculations quickly.
Existentialism is a philosophical theory that explores the search for meaning and values in life. It emphasizes individual freedom and the responsibility to create one's own meaning in a seemingly meaningless world. Existentialists believe that human beings must confront the inherent absurdity and uncertainty of existence in order to find purpose and fulfillment.
The main need to work with grouped data was to reduce the number of data points that need to be stored and processed in calculation. With modern computers the storage and computation are not likely to be issues in many situations and so there is no need to use grouped data.

You will need to put the un-grouped data in ascending or descending order. If you have an odd number of data values the formula for the median value is (n+1)/2. Example my data in ascending order is 0, 2, 4, 5, 7, 8, 9. I have 7 data values. The median is the value (7+1)/2 = 4th value from left or right which is 5. For an even number of data values, you will need to calculate the median and it may not be a data value. It will be the mean of the two center values. Use the formula n/2 to get the left most value. Example my data in ascending order is 0, 2, 4, 5, 7, 8. I have 6 data values. The left most value I will use to calculate the median is 6/2 = 3rd. The 3rd value from the left is 4. The next value is 5. Median is (4+5)/2 = 4.5.
Select a set of x values and find the value of y or f(x) - depending on how the parabola is defined. These are the values that you need to graph.
