A linear grade distribution takes the lowest grade, sets it equal to your set minimum; and takes the highest grade and sets it to your set maxiumum.

Any other grades are scaled between these two points. This page will allow you to enter your grades and it will rescale them to fit in that range. Enter the grades in the box below, one per line.

The curve is also called the Gaussian curve after the German mathematician Carl Friedrich Gauss, who discovered many of the curve's properties. A graphed curve approximates the range and counts for many actual observations of facts that exist in nature and in civil society, such as weight and educational performance. Choose the fact you want a normal probability distribution for.

Consider how the example of normal occurrences will help you come to a conclusion. Resolve the decisive questions about your fact. Is a normal weight distribution useful to studying the weights in a medical patient population? Or is the population too unusual or abnormal to use a normal curve? Make a data set for your the observations you plan to chart. For each subject, take down the fact as a numerical value. Assign the number range for the numerical values, using the lowest observation to the highest observation.

Use the bell curve formula to calculate the y axis value for each x axis value. Y is the number of observations for an x value. The x is an observed value. Use the x sub order number for the calculation order and list order. Make a table of x values and the corresponding y values. Graph the bell curve for your fact. Using graph paper, arrange a graph with an x axis and a y axis. Draw the axis range to begin at your lowest value and end at your highest value.

Begin the y axis at 0, for no observations, and end at the greatest number of potential observations for any x value. The greatest potential observations is the highest number you believe you could find for your fact; for example, the highest number of male patients with a weight of pounds. When you want to compare your observed facts to a normal distribution, view a graph of your observations and the normal curve you graphed. Compare how the actual observations fall in the areas within one standard deviation of the mean.

When you have a good data set for a normal population, 90 percent of your observations fall within 1. Differences form the normal curve tell you your population is above average, when the mean for the actual observations is to the right, or below average, when your observed mean is to the left. For facts that have normal distributions in the population, the higher your number of observations--assuming you have a random sample--the closer the observed curve will be to the bell curve.

Note that your bell curve does not have the two long tails, to the left and to the right, that the theoretical bell curve has. You curve has limits at the lowest and highest observed x values.

Things You'll Need.An online bell curve calculator to generate a normal distribution curve and its value.

Enter the mean, standard deviation and select whether left tailed or right tailed or two tailed in this normal distribution curve generator to get the result. Bell Curve: 'Bell curve' is a curve in the shape of a bell in the graph sheet, obtained as a result of the normal distribution, also referred to as Gaussian distribution. It is created when a line is plotted using the data points for an item that meets the criteria of 'normal distribution'.

Normal Distribution: Normal distribution, also known as Gaussian distribution, is used in social sciences to represent real-valued random variables whose distribution are not known.

Here all the values are plotted in a symmetrical fashion, with most of the results or values situated around the probability's mean.

This online bell curve calculator will help you dynamically calculate the Gaussian distribution value and to draw the bell curve online. In this normal distribution curve generator, you can set the whether the curve should be 'left tailed' or 'right-tailed' or 'two-tailed' by entering appropriate values lesser than or greater than X.

It also shows plots, alternate forms and other relevant information to enhance your mathematical intuition. Enter your queries using plain English. To avoid ambiguous queries, make sure to use parentheses where necessary. Here are some examples illustrating how to ask for an integral. Get immediate feedback and guidance with step-by-step solutions and Wolfram Problem Generator.

The indefinite integral ofdenotedis defined to be the antiderivative of. In other words, the derivative of is. Since the derivative of a constant is 0, indefinite integrals are defined only up to an arbitrary constant. For example, since the derivative of is. The definite integral of from todenotedis defined to be the signed area between and the axis, from to.

Both types of integrals are tied together by the fundamental theorem of calculus. This states that if is continuous on and is its continuous indefinite integral, then. This means. Sometimes an approximation to a definite integral is desired.

A common way to do so is to place thin rectangles under the curve and add the signed areas together. Wolfram Alpha can solve a broad range of integrals.

Wolfram Alpha computes integrals differently than people. It calls Mathematica's Integrate function, which represents a huge amount of mathematical and computational research. Integrate does not do integrals the way people do. Instead, it uses powerful, general algorithms that often involve very sophisticated math. There are a couple of approaches that it most commonly takes.

One involves working out the general form for an integral, then differentiating this form and solving equations to match undetermined symbolic parameters. Even for quite simple integrands, the equations generated in this way can be highly complex and require Mathematica's strong algebraic computation capabilities to solve. Another approach that Mathematica uses in working out integrals is to convert them to generalized hypergeometric functions, then use collections of relations about these highly general mathematical functions.

While these powerful algorithms give Wolfram Alpha the ability to compute integrals very quickly and handle a wide array of special functions, understanding how a human would integrate is important too.

As a result, Wolfram Alpha also has algorithms to perform integrations step by step. These use completely different integration techniques that mimic the way humans would approach an integral. This includes integration by substitution, integration by parts, trigonometric substitution and integration by partial fractions.
