What is the normal curve for an IQ test?

Why does a researcher want to go from a normal distribution to a standard normal distributio?
A normal distribution simply enables you to convert your values, which are in some measurement unit, to normal deviates. Normal deviates (i.e. z-scores) allow you to use the table of normal values to compute probabilities under the normal curve.
Why the central limit theorem tells us that it is OK to use the normal distribution to determine probabilities of x?
The Central Limit Theorem (CLT) says no such thing! In fact, it states the exact opposite.The CLT sets out the conditions under which you may use the normal distribution as an approximation to determine the probabilities of a variable X. If those conditions are not met then it is NOT OK to use the normal distribution.
What is the difference between curve fitting and regression?
curve fitting is a very difficult and time wasting method while regrresion is more to use as compare to curve fitting
Compare the mode mean and median to determine which is the best to use?
The mode is the most probable value, or the peak of the probability distribution curve. There might be more than one mode if the curve has more than one peak. The mean is the arithmetic average of all obervations. If the probability curve is symmetrical, the mean will be the same as the mode, or the same as the average of the modes. The median is the average of the two furthest outliers. Again, if the curve is symmetrical, the median, mode, and mean are all equal. Outliers, errors, fluctuations, assymmetries - they all change or tilt the results. Which method you use depends on what you want to know, and on how you want to use the results.
How can one determine the concentration of a sample using a calibration curve?
To determine the concentration of a sample using a calibration curve, you first need to measure the response of known standard samples with known concentrations. Then, plot a calibration curve by graphing the response against the concentration. Finally, measure the response of the unknown sample and use the calibration curve to determine its concentration by finding where its response falls on the curve.
What must be done to a normal curve to make it into a standard normal distribution curve?
The mean must be 0 and the standard deviation must be 1. Use the formula: z = (x - mu)/sigma
What must be true about data in order to use the tools of the normal curve?
it must be normally distributed
How can one determine the equivalence point on a titration curve in Excel?
To determine the equivalence point on a titration curve in Excel, you can identify the point where the slope of the curve is steepest. This is where the concentration of the titrant is equal to the concentration of the analyte being titrated. You can use Excel to plot the titration data and calculate the derivative of the curve to find the point of maximum slope, which corresponds to the equivalence point.

How to calculate the radius of curvature for a given curve?
To calculate the radius of curvature for a given curve, you can use the formula: ( R frac1 (dy/dx)23/2d2y/dx2 ), where ( dy/dx ) represents the slope of the curve and ( d2y/dx2 ) represents the second derivative of the curve. This formula helps determine how sharply the curve is bending at a specific point.
How can one determine the normal force in physics?
To determine the normal force in physics, you can use the equation: Normal force mass x acceleration due to gravity. The normal force is the force exerted by a surface to support an object resting on it. It acts perpendicular to the surface.

What is the Criterion to check that the curve is best linearly fitted or not?
Determine the Correlation Coefficient. These are tedious calculations, so it is best to use statistics programs or calculators.
Why you use semi-log graph over normal graph?
why would you use a semi-logarithmic graph instead of a linear one?what would the curve of the graph actually show?
How can one calculate the unknown concentration from a standard curve?
To calculate the unknown concentration from a standard curve, you first need to plot a graph with known concentrations and corresponding measurements. Then, you can use the equation of the line to determine the concentration of the unknown sample based on its measurement.
How can one determine the magnitude of the normal force acting on an object?
To determine the magnitude of the normal force acting on an object, you can use the equation: Normal force mass x acceleration due to gravity. The normal force is the force exerted by a surface to support the weight of an object resting on it. It acts perpendicular to the surface.
