You draw a series of line segments joining the points which would be the middle of the top of each bar of the histogram.

Difference between histogram and frequency polygon?

They are the same thing except that in a histogram you are using bars (like in a bar chart) to show the frequency, while a polygon uses points connected by straight lines The way I have the students do it is to plot the x,y coordinates for your data ( x is the value of the random variable, y is the frequency ) If you are doing a frequency polygon, you just connect the dots with straight lines (you need to start at zero to the left of your first point and to the right of your last point) If you are doing a histogram, just draw bars where the middle of each bar comes up to the x,y point


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


Can any set of data be displayed using a histogram?

Yes, any data set can be displayed using a histogram, as long as it represents original data, or data that does fall in a particular order.


Is it possible to determine the mode of data set using a histogram?

Yes.

What is frequency polygon?

A frequency polygon is a simple way of representing quantitative data. It is usually used for ungrouped data (a histogram is more commonly used for grouped data). It is a plot of points whose x-coordinate represents values that are observed and the y-coordinate is a count of the number of times the value was observed. These points are joined together using straight lines to form the frequency polygon. Often the first point is joined to a point on the x-axis that is one unit before the x-coord of the first point, and the last point is joined to a point on the x-axis that is one unit after the x-coord of the last point to complete the polygon.

What are the advantages of using the histogram instead of the box plot to represent the data?

A histogram can handle data when the bars are not all of the same width. This is particularly important for data which are skewed.


Why it important to display data using a histogram?

It makes Data simpler to compare as opposed to a chart

What is a characesteristic of a regular tessellation?

A regular tessellation is one in which a plane is covered, without gaps or overlaps, using copies of a regular polygon.
