What is the mean and standard deviation for the standard normal curve?

Mean = 0 Standard Deviation = 1


What is the standard deviation of the stardard normal curve?

1


Is normal curve symmetrical about its standard deviation?

nop its not


How do you apply standard deviation to normal curve?

The distance between the middle and the inflection point is the standard deviation.


What is the difference between a general normal curve and a standard normal curve?

A standard normal distribution has a mean of zero and a standard deviation of 1. A normal distribution can have any real number as a mean and the standard deviation must be greater than zero.


What is the standard deviation of the normal IQ curve?

It is 15 points.


Which normal distribution is also the standard normal curve?

The normal distribution would be a standard normal distribution if it had a mean of 0 and standard deviation of 1.


Is it true that The smaller the standard deviation of a normal curve the higher and narrower the graph?

Yes, that's true. In a normal distribution, a smaller standard deviation indicates that the data points are closer to the mean, resulting in a taller and narrower curve. Conversely, a larger standard deviation leads to a wider and shorter curve, reflecting more variability in the data. Thus, the standard deviation directly affects the shape of the normal distribution graph.


Is the normal distribution always being defined by the mean and standard deviation?

Yes, the normal distribution is uniquely defined by its mean and standard deviation. The mean determines the center of the distribution, while the standard deviation indicates the spread or dispersion of the data. Together, these two parameters specify the shape and location of the normal distribution curve.


Why don't all normal curves have the same standard deviation?

Because the standard deviation is one of the two parameters (the other being the mean) which define the Normal curve. The mean defines the location and the standard deviation defines its shape.


When the larger values of the standard deviation result in a normal curve that narrower and more peak?

Smaller


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
