Here we have given data set of 40 observations.
We have to construct frequency distribution of the data.
Make 8 classes having first lower limit will be 15.
Lets find width of the interval.
Range = Maximum - Minimum = Width = 37
WIdth = 37 / 8 = 4.625 which is approximately equal to 5.
SO the first class will be 15-20, second will be 20-25, third will be 25-30,............ and so on.
Now we have to find frequency for each class.
Frequency is number of observations fall in particular class.
There are 18 observations in the first class, 10 observations in the second class,............... and so on.
In this way we find all the frequencies and completing the frequency distribution.
Now we have to construct histogram of the given frequency distribution.
Histogram in Statcrunch :
steps :
1. Enter the raw data into the spreadsheet. Name the column variable.
2. Select Graphics and highlight Histogram.
3. Click on the variable you wish to summarize and click Next>.
4. Choose the type of histogram (frequency or relative frequency). You have the option of choosing a lower class limit for the first class by entering a value in the cell marked “Start bins at:”. You have the option of choosing a class width by entering a value in the cell marked “Binwidth:”. Click Next>.
5. You could select a probability function to overlay on the graph (such as Normal – see Chapter 7). Click Next>.
6. Enter labels for the x- and y-axes, and enter a title for the graph. Click Create Graph
The shape will be same for both the graphs because data is same.
Histogram shows positively skewed shape.
