The normal distribution is a valuable statistical concept used to assess the average distribution across a range of data. This is particularly beneficial for professionals like mathematicians, physicians, and those working in finance. Another helpful resource at their disposal is the WPS Spreadsheet. It stands out due to its user-friendly features. In this guide, we'll walk you through the process of calculating the NORM.DIST in Excel in the WPS Office, providing a practical tool for professionals in these fields.
What is Excel's "NORM.DIST" Function?
NORMDIST, a built-in statistical function in Excel, is a powerful tool for analyzing data distributions based on the principles of normal distribution, also known as the Gaussian distribution. This function comes to your aid when you possess a dataset characterized by a known mean and standard deviation. With NORMDIST, you can seamlessly calculate the probability of a random variable falling within a specific range, essential for various probability and statistics applications.
Users can take advantage of the NORM.DIST function Excel in WPS Office as well, a powerful and versatile alternative to Microsoft Excel. To make effective use of Excel Normal Distribution Function in WPS Office, we need to understand the syntax and its arguments.
Syntax
=NORM.DIST(x, mean, standard_dev, cumulative)
“x”= The point for which you want the distribution
“mean”= The mean (average) of the dataset.
“standard_dev”= The standard deviation (dispersion) of the dataset.
“cumulative”= A cumulative value that dictates whether the function calculates the cumulative distribution (probability of being below the X value) or the probability density (likelihood of the exact X value)
How to Use the "NORMDIST" Function in WPS Office?
To understand how the Excel NORMDIST function in WPS Office works, it is best to take the help of an example.
Example 1- Cumulative Distribution Function
Imagine a pharmaceutical company with a team of 10 salesmen. The company has gathered data on its monthly sales figures. Let's say the mean (average) monthly sales for these salesmen is $20,000, and the standard deviation is $3,000. We want to calculate the probability of a salesman achieving sales of $22,000 or less in a given month using the NORMDIST function in Excel.
In this example, since we want to calculate the probability of a salesman achieving sales of $22,000 or less, we will be using the cumulative distribution function. This means that our “Cumulative” argument will be “True”
Step 1: Click on an empty cell to calculate the Normal Distribution of the data.
Step 2: Enter the Excel NORMDIST function starting with an Equals sign; “=NORM.DIST()”
Step 3: Select cell B2 for our x argument. We want to calculate the probability of $22,000 or lower, therefore, “x” will be $22,000.
Step 4: Next, the mean in our example is $20,000, therefore, we will be selecting cell B3 for our mean argument.
Step 5: Then we have the standard deviation, which is $3,000 in our example. Hence we will be selecting cell B4.
Step 6: As we need the cumulative distribution function, we will be setting our final argument as “TRUE”. Once done, hit “Enter”.
Step 7: The normal distribution will then be displayed in cell B5.
From our results, we can interpret that the probability of a salesman achieving sales of $22,000 or less is 0.7475 or 74.8%. In mathematical terms P(X≤$22,000) = 0.07475
Example 2- Calculating the Probability of Values Greater Than X
What if we want to calculate the probability for values greater than X? We will simply subtract it from 1. Let’s say we want to calculate the probability of a salesman achieving sales greater than $22,000.
Step 1: Using the same example as above, we will simply just subtract our probability from 1.
Step 2: Upon pressing “Enter” our results will be displayed.
Looking at our results we can say that, the probability of a salesman achieving sales greater than $22,000 is just 0.252 or P(X>$22,000)=0.252.
Example 3- Probability Density Function
Using the same example as above, if we try calculating the probability of a salesman achieving sales equal to $21,500, we will be using the Probability Density Function.
Step 1: Click on cell B5; empty cell.
Step 2: Enter the same NORMDIST function with X= $21,500. Mean= $20,000 and Standard_dev= $3,000.
Step 3: For our last argument, we will be entering “FALSE” as we are calculating the Probability Density Function and then press “Enter”.
Step 4: WPS Office will calculate the Normal Distribution accordingly and display the results.
According to the results, the P(X=$21,500) = 0.000117.
Example 4: Probability of Sales in Between Two Values
Here, we will try to calculate the probability of a salesman achieving sales between $21,500-$22,500. This can simply be done using the NORMDIST calculator in Excel using WPS Office.
Step 1: We will enter the same NORMDIST function with the X, Excel NORMDIST mean, and Standard Deviation but for the bigger X value first.
Step 2: Insert the subtraction symbol followed by the same NORMDIST function but this time for the smaller value of X.
Step 3: Once you hit “Enter”, WPS Office will display the results.
The probability of a salesman achieving sales in between $21,500-$22,500 is 0.106. P($21,500≤X≤$22,500)=0.106

Q1. What are Distance Metrics in Vector Search?
In vector search, distance metrics are functions that help to estimate the distance between two vectors in a vector space. You can make use of these metrics to compare the similarity or dissimilarity of two vectors. The distance comes in various forms. For instance, it could be the geometric distance between two points, the angle between vectors, or the count of vector component differences. In vector search, a few widely used distance measures include Euclidean distance, cosine similarity, dot product similarity, Manhattan distance, and Hamming distance.
