What else can I help you with?
What happens as the number of classes in a histogram decreases?
central tendancy gets more obvious
The width of each bar in histogram corresponds to the?
number of classes
What happens as the number of classes in a histogram increase?
The columns become narrower, their heights become more accurate but possibly more variable. The chart contains more of the underlying detailed information.
The suggested interval size of the class intervals for a histogram can be estimated by?
highest value-lowest value/number of classes
Sketch a relative frequency histogram for the 36 sample means Use nine classes In this histogram approximately bell shaped and symmetric?
you have to find the class size by: (max-min)/number of classes Then use that class size to setup the class ranges Then use the class ranges to determine the frequency a sample occurs in each class. make a chart using the class ranges and the sample frequencies to display the histogram

How do i determine the number of classes ie intervals estimate the frequency of the class with the least and greatest frequency and determine the class width on a histogram?
try sqrt(N) where N represents the number of observations you have...

What happens to the temperature increase the number of particles what happens to the pressure?
Increasing the temperature the number of particles remain constant and the pressure increase.
How do you find the median in a histogram?
i think you divide the histogram in two, so there are two equal halves. The number in the middle is the median,
When creating a histogram it's important to ensure that the classes of data satisfy which properties?
When creating a histogram, the classes of data should be mutually exclusive, meaning each data point must fall into one and only one class. Additionally, the classes should be exhaustive, covering the entire range of the data without gaps. The classes should also be of equal width to maintain consistency in representation, unless using variable-width bins to highlight specific data distributions. Finally, the number of classes should be appropriate to balance detail and clarity, avoiding overly cluttered or overly simplified representations.
Explain why the discrete histogram equalization technique does not generally yield a flat histogram?
All that histogram equalization does is remap histogram components on the intensity scale. To obtain a uniform (­at) histogram would require in general that pixel intensities be actually redistributed so that there are L groups of n=L pixels with the same intensity, where L is the number of allowed discrete intensity levels and n is the total number of pixels in the input image. The histogram equalization method has no provisions for this type of (arti®cial) redistribution process.
