What else can I help you with?
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...
The width of each bar in histogram corresponds to the?
number of classes
What happens as you increase the number of classes in a histogram?
central tendency become more obvious
What happens as the number of classes in a histogram decreases?
central tendancy gets more obvious
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 you determine the number of values in a data set using a histogram?
by using your brain

The suggested interval size of the class intervals for a histogram can be estimated by?
highest value-lowest value/number of classes
Here is the histogram of a data distribution The classes all consist of just one number the class width is 1 Which of the following numbers is the median of this distribution?

Does the central tendency of a class become more obvious as you increase classes in a histogram?
Yes!
Is it possible to determine the mode of data set using a histogram?
Yes.
Here is the histogram of a data distribution The classes all consist of just one number the class width is 1 Which of the following numbers is closest to the mean of this distribution?
5
Is a histogram a graph that represents the cumulative frequencies for the classes in a frequency distribution?
No it is not. The ogive is a graph that represents the cumulative frequencies for the classes in a frequency distribution.
