Final answer:
The Closed interval method in creating histograms involves constructing the histogram with five to six intervals, sketching it accurately with a ruler and pencil, and scaling the axes properly.
Step-by-step explanation:
The Closed interval method is a technique used in constructing histograms, which are graphical representations of the distribution of numerical data. To apply this method, follow these steps:
Construct a histogram by creating five to six intervals based on the data set.
Sketch the graph using a ruler and pencil to ensure straight lines and accurate proportions.
Scale the axes appropriately so that they represent the range of data and the size of intervals correctly.
Keep in mind that when plotting the data on the histogram, a value that falls on the left boundary of a class interval is included in that interval, but if it falls on the right boundary, it is not included. There may be variations in how histograms are constructed, but the key is to consistently apply the chosen method.
Construct a histogram using the given data.
Divide the data into five to six intervals to create equal-sized groups.
Sketch the graph of the histogram using a ruler and pencil.
Scale the axes appropriately to represent the data accurately.
