In a histogram, the boundaries of a class, also known as bins or intervals, define the range of data values that fall within each category. Each class boundary specifies the lower and upper limits of the interval, and data points that fall within these limits are counted toward the respective bin. Typically, class boundaries are set to ensure that there are no gaps between adjacent bins, and they help in organizing continuous data into discrete categories for better visualization and analysis. Properly defining these boundaries is crucial for accurately representing the distribution of the dataset.
What else can I help you with?
An interval on a relative frequency histogram?
CLASS
What does the width of each bar in a histogram corresponds to?
The class interval.
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 work out the frequency for a histogram?
Frequency Density multiplied by the class width
What is an interval on a relative frequency histogram?
I think the answer is class and... go ask the teacher or flunk
What are the ranges of data in a histogram?
They are the class boundaries.
How do you find the range on a histogram?
The range is largest of all the class boundaries minusthe smallest.
Which class boundary choice below would cause a histogram of these data to present the appearance of a uniform distribution?
Choosing wider class boundaries would cause a histogram of the data to present the appearance of a uniform distribution. This is because the data points within each wider class would be spread out more evenly, giving the histogram a more uniform look.
What information is found in a histogram and not in a box-and-whiskers plot?
The answer will depend on the histogram. If the histogram consists of four intervals whose boundaries are the quartiles of the distribution, then it will contain exactly the same information.

Do the formula for calculating mode from histogram existed?
as mode means the value occurring most no. of times we can determine the mode from histogram, looking which class has the maximum frequency!

Does the central tendency of a class become more obvious as you increase classes in a histogram?
Yes!
What does the height of a bar in a histogram represent?
The frequency density. That is, the frequency divided by the class width.
