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.
What else can I help you with?
The width of each bar in histogram corresponds to the?
number of classes
What happens as the number of classes in a histogram decreases?
central tendancy gets more obvious
What happens as you increase the number of classes in a histogram?
central tendency become more obvious
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.
What is the difference between bar and histogram?
Bars are for single values or classes with uniform width, and the height of each bar is the frequency. In a histogram, the classes are of different width and the heights are proportional to the frequency density. The frequency, itself, is given by the area of the "bar" above the class.

Does the central tendency of a class become more obvious as you increase classes in a histogram?
Yes!

Why are periodic tables important in most scientific classes?
Periodic tables are important in most scientific classes because they help understand similarity of properties and reactions of elements.
What is the name of the ranges of data in a histogram?
They are often called classes butt may have more specific names.

The suggested interval size of the class intervals for a histogram can be estimated by?
highest value-lowest value/number of classes
Suppose that a frequency histogram and a cumulative frequency histogram are constructed from the same set of data using the same classes is the frequency for each class is the frequency equal to the?
the frequency is less than OR EQUAL TO the cumulative frequency
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
