A standard normal curve provides both a visual and a numerical representation of how a given variable is distributed across a population when the real-life situation represented by the function is known to have a symmetrical distribution in the population of interest (hence the "bell" shape). Th...

If you monitor the pH throughout a titration, you can plot your data afterward to make a graph called a titration curve. Use this curve to figure out the concentration of the chemical in the solution for analysis, also called the analyte. The point on the titration curve at which all of...
You may need to use a basic calculator to find the square root. Be sure to usesignificant figureswhen rounding your final answer. A Worked Example Suppose you're given the data set 1, 2, 2, 4, 6. Work through each of the steps to find the standard deviation. Calculate the mean of ...
Recall the properties of thebell curveand the probabilities from astandard normal distribution. One feature has to do with the amount of data that falls within a certain number of standard deviations: Approximately 68% of the data is within one standard deviation (higher or lower) from the mean...
This guide will show you how to calculate the probability (area under the curve) of a standard normal distribution. It will first show you how to interpret a Standard Normal Distribution Table. It will then show you how to calculate the:...

How Do I Calculate the Mode? Calculating the mode is fairly straightforward. Place all numbers in a given set in order—this can be from lowest to highest or highest to lowest—and then count how many times each number appears in the set. The one that appears the most is the mode. ...
In this tutorial, I will show you how to calculate the standard deviation in Excel (using simple formulas) But before getting into, let me quickly give you a brief overview of what standard deviation is and how it’s used. Sorry, the video player failed to load.(Error Code: 101101) Thi...
Method 1 – Calculate the Area Under the Curve with the Trapezoidal Rule in Excel It is not possible to directly calculate the area under the curve. We can break the whole curve into trapezoids. By adding the areas of the trapezoids, we can get the total area under the curve. STEPS: ...
