If the Z-Score corresponds to the standard deviation, then the distribution is "normal", or Gaussian.

What is the normal curve for an IQ test?
just use your brain and study be smart think and double check your work
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.
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

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?
What are the pros and cons of management's using the experience curve to determine strategy?
Management's use of an experience curve could help them avoid costly risks. However, repeated actions must be performed in this management style which could push production efforts back.

How do you make a rounded object on Google Sketchup?
Use the Arc Tool. First make a line from one end of the arc to the other. Then, move the mouse outwards to determine the curve.
What kind of curve does Patrick Kane use?
P88. He uses his own stick curve.
How do you find the surface area of a shoe?
Treat the sole as a rectangle. measure length and width. If there is a curve, estimate center of curvature. measure radius. measure length of curve in arc lengths. Determine number of radians. use formula for cylinder, replacing 2 (pi) with number of radians. Subtract length of shoe by the length of curve in the sole. Calculate area
