How do you find the upper and lower quartile for a histogram with unequal class widths?
Bettyoo8
You would first need to know the amounts of each quartile. Then use your formula to place the numbers inside.

What is the difference between graph and histogram?
A histogram is a very specific type of graph. A histogram is used in statistics to plot grouped data. It is in the form of a bar chart in which the bar widths represent the class intervals and the bar heights represent the frequency densities. As a result, the area of each bar is proportional to the frequency.
When to use a histogram?
Histograms are relatively similar to line plots; A bar graph of a frequency distribution in which the widths of the bars are proportional to the classes into which the variable has been divided and the heights of the bars are proportional to the class frequencies.noun
When drawing frequency distribution histograms what does it mean when the distribution is broken?
A histogram is "a representation of a frequency distribution by means of rectangles whose widths represent class intervals and whose areas are proportional to the corresponding frequencies.Broken distribution means that no data point falls in that class.
An interval on a relative frequency histogram?
CLASS
What does the width of each bar in a histogram corresponds to?
The class interval.
When do you use histogram graph?
Histograms are generally used when quantitative information is presented for groups (classes) of different sizes (class widths).

What do you mean by histogram?
A histogram is a chart comprising bars but, unlike an ordinary bar chart, the widths (intervals) of the bars are different and their heights represent the frequency densities, not frequencies.

What are the ranges of data in a histogram?
They are the class boundaries.
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
What is The distance between consecutive lower class limits is called the?
They are the class widths.
How do you work out the frequency for a histogram?
Frequency Density multiplied by the class width
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!
