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."
To find the missing mean in a set of data, you first need to know the sum of all the values in the data set as well as the total number of values. Once you have this information, you can calculate the missing mean by dividing the sum of all the values by the total number of values. This will give you the average value of the data set, which is the missing mean.
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.
To find the missing number in a data set with a mean of 15, you need to know the total number of values (n) in the data set and the sum of the existing numbers. The mean is calculated as the sum of all values divided by n. If you have the sum of the existing numbers, you can rearrange the formula: missing number = (mean × n) - sum of existing numbers. Without additional information, the exact missing number cannot be determined.

To determine the uncertainty of measurement in a scientific experiment, you need to consider factors like the precision of your measuring tools, the variability of your data, and any sources of error in your experiment. Calculate the range of possible values for your measurements and express this as an uncertainty value, typically as a margin of error or standard deviation. This helps to show the reliability and accuracy of your results.
To find the lower extreme, you need to identify the smallest value in a data set. To find the upper extreme, you need to identify the largest value in the data set. These values represent the lowest and highest points of the data distribution.
To measure uncertainty, you need to know the precision of the instrument, which refers to the smallest unit that an instrument can measure. A measurement can then be represented with its associated uncertainty, such as X = (5 +/- 1) cm. In this case, the actual value can deviate from the mean (5cm) by 1cm, so the minimum and maximum values ate 4cm and 6cm respectively. The percentage uncertainty is calculated by (absolute uncertainty / mean value) * 100%.
To find the uncertainty in a measurement, you need to consider the precision of the measuring instrument and the smallest unit of measurement it can detect. This uncertainty is typically expressed as a range around the measured value, indicating the potential error in the measurement.
No, they need not.
The greater the sampling error the greater the uncertainty about the results and therefore the more careful you need to be in the interpretation.

You don't know how much need there is out there for your service or product.
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.
Extrapolation involves predicting values outside of the range of known data, while interpolation involves estimating values within the known data range. Extrapolation assumes that the pattern observed in existing data continues beyond what is measured, which can lead to more uncertainty compared to interpolation. Interpolation, on the other hand, is used to estimate values between existing data points.
