The Bell Curve, also known as the Normal Distribution Curve, is a graph that represents the distribution of a variable. We observe this distribution pattern frequently in nature. For example, when we analyze exam scores, we often find that most of the scores cluster around the middle. Here ...

Since the data points of a normal distribution are clustered around the mean, it is more useful to measure the variance of each data point from the central mean rather than its absolute value. And plotting these variances in the form of a graph yields a Bell Curve. This allows you to spo...
You can see that the graph is not perfectly bell-shaped. That's because the dataset (student's marks) is not normally distributed (i.e. the mean, median, and mode of the dataset are not the same.) 3. Customizing the Bell Curve We already have our bell curve, but we can make it ...

A graph that represents the density function of the Normal probability distribution is also known as a Normal Curve or a Bell Curve (see Figure 1 below). The Normal distribution requires two parameters, the mean and the standard deviation. A Normal distribution with a mean of zero and a stan...
The "curve" referred to in the term is the "bell curve," which is used in statistics to show the normal distribution—what the expected variation is—of any set of data. It's called abellcurve because once the data is plotted on a graph, the line created usually forms the shape of ...
We have seen above that the shape of the bell curve is not perfect. This is because the difference between the values on the X-axis (marks of the students) is not the same. Now, we are creating one more bell graph with equally spaced values on the X-axis. You have to follow the ...
This voltage reading is recorded and is plotted on a graph for comparison and further analysis. It gives a bell-shaped curve, and the area under the curve gives the relative concentration of molecules. This area is used to calculate the tracer quantity recovered. Gases used for ignition in ...
