We will discover how to find uncertainty in Google Sheets in this article. Since it indicates the level of confidence in computation or measurement, uncertainty is a crucial term in statistics for data analysis and decision-making.
Depending on the type of data and the goal of the research, there are a number of techniques to discover and quantify uncertainty in Google Sheets. This tutorial will show how to find uncertainty in Google Sheets built-in methods and perhaps some custom formulas to determine uncertainty in Google Sheets. We will discuss the fundamentals of uncertainty, and I will demonstrate how to use generic concepts like error propagation and confidence intervals with various forms of data, including measurements, estimates, and projections.
By the end of this tutorial, you will be equipped with the knowledge and abilities to identify and understand uncertainty in your own data sets and to base your judgments on your findings in a more informed manner.
Why is it Important to Learn How to Find Uncertainty in Google Sheets
There are several reasons why we would need to determine the level of uncertainty in a set of data. Uncertainty is a necessary component of all data sets for data analysis, and it’s important to understand how it influences the outcomes of your calculations and analysis. Knowing how to locate and measure uncertainty in Google Sheets can help you express a degree of confidence in your findings to others and make more educated decisions based on your data. When you execute calculations on uncertain data, the uncertainty in the input data will propagate through the calculations and affect the uncertainty in the final outputs, which is comparable to error propagation.
You’ll receive more accurate results if you know how to find uncertainty in Google Sheets correctly. Confidence intervals, which are a range of values that, with a particular level of confidence, are likely to include the true value, are another thing. Confidence intervals can be calculated by identifying uncertainty.
These are a few justifications for learning how to find uncertainty in Google Sheets.

How to Find Uncertainty in Google Sheets
In Google Sheets, there are a ton of built-in functions that may be utilized in different ways to discover doubts. However, despite the fact that their major objectives differ and they are not the same, you can utilize any of them, depending on your problem, to identify confusion. I will therefore demonstrate how to utilize each of these functions and provide examples of each finding’s uncertainty for a sample data set.
How to Find Uncertainty in Google Sheets – Through Using STDEV
Despite the fact that STDEV stands for standard deviation and is employed to determine the standard deviation based on a sample. However, the amount of uncertainty is also a component of it, and we can use this function to determine it for a particular data set.
The syntax is quite basic: =STDEV(value1, [value2, …])
- value1 – The sample’s initial value or range.
- Additional values or ranges to include in the sample are indicated by value 2.
- The data set must only be passed into the function once for us to receive the data’s uncertainty.
Step 1>
Obtain some test data.
Step 2>
In the cell that follows in your file, enter the STDEV function.
Step 3>
If you have more values, you can add up to 30 optional values separated by commas, but you must pass the complete range or cell as the input.
Step 4>
When you press the Enter key, a numeric value that can be used to describe the data’s uncertainty will appear.
How to Find Uncertainty in Google Sheets – Through Using STDEVP
We also have STDEVP for the population, much like STDEV. This section explains how to use the STDEVP function in Google Sheets to find uncertainty. This is a standard deviation function as well, but it also has the ability to reveal the degree of uncertainty in the supplied data.
The sole difference between these two functions’ syntax is the type of data you have. If you have sample data, use STDEV; if you have population data, use STDEVP.
Step 1>
The STDEVP function should be entered in a cell in your Google Sheets file.
Step 2>
If necessary, pass optional values in addition to the required parameter.
Step 3>
When you press the Enter key, a value will appear that represents the dataset’s level of population data uncertainty.
How to Find Uncertainty in Google Sheets – Through Using PROB Function
You must have heard that statistics and probability were studied in college. Although it may seem uninteresting to you, it is actually quite interesting and is currently used in cutting-edge technologies like big data and data science. To determine the probability of a given data set, we can utilize the straightforward prob function in Google Sheets. Be focused and cautious when supplying your data because this function has various input restrictions.
Considering that this is a new feature we are discussing here. Let’s discuss it in greater detail.
Formula (Syntax) =PROB(data, probabilities, low_limit, [high_limit])
The argument enclosed in square brackets is not required.
- data: Data that you want to compute the probability for, either in the form of an array or a data range.
- Probabilities: Data ranges or direct values for probabilities of the data are known as probabilities.
Note: The values inside the probability argument must be larger than 0 and must not be greater than 1, according to the mathematical rule.
- low_limit: The lowest possible value for the data point for which we wish to estimate the probability.
- high_limit: It’s not required. It is the upper limit on the data values for which we want to calculate the probability, and if it is not supplied, the function treats it as the value of the low limit.
Note: Both the probability argument and the data argument must have the same number of values.
These are examples of how to use this function.
=PROB({1,2,3,4},{0.25,0.25,0.25,0.25},3)
=PROB(A2:A100,B2:B100,C2,C3)
Step 1>
I’ve got some simple sample data here for this example.
Step 2>
We will input values into the function while keeping in mind the prob function’s rules.
Step 3>
We obtain the probability for our dataset in this manner.
There is a generic meth formula we can use to find uncertainty. It can be used inside Google Sheets to determine the level of uncertainty there.
How to Find Uncertainty in Google Sheets – Using Uncertainty Custom Formula
This section will teach you how to use a general statistics method to find uncertainty in Google Sheets. In order to use this custom formula, we will need to employ a few additional built-in Google Sheets methods, so let’s get started with this section and learn how to find uncertainty in Google Sheets.
The formula (syntax) for uncertainty: =Uncertainty (u) = √ [∑ (xi – μ)2 / (n * (n – 1))]
Learn Formula,
-
xi = reading over the data set
-
μ = The data set’s mean
-
n = Readings included in the data set
Situational Statement
First, we need to understand the problem statement in order to comprehend the uncertainty. So let’s say that at the picnic area, there was a running contest among the children that was timed by five different stopwatches. In the end, each stopwatch produced a slightly different result that differs only a little in terms of time. Now that we have the data and timing with a 68% confidence level, we must compute the timing’s uncertainty.
Step 1>
In this case, the first argument is the fifth reading in the data set, or 5, as each stopwatch has five separate values.
Step 2>
The mean will be determined by adding together all the reading values and dividing them by the number of readings, which in this case is 5.
Step 3>
The standard deviations of each reading must now be determined. For each reading, we will use the Reading-Mean formula.
Step 4>
The square of each reading’s deviations must now be calculated. We may achieve this by merely multiplying each reading by itself.
Step 5>
Everything is now ready for our uncertainty formula.
This formula is used to calculate uncertainty: =Uncertainty (u) = √ [∑ (xi – μ)2 / (n * (n-1))]
Step 6>
This is how uncertainty in Google Sheets is found; you can see the final formula and the results of the readings we obtained from it below.
