Why it is more useful to draw a graph then a table?
Though a table contains the data, it needs to be studied carefully. A graph, on the other hand, is an easier way to graphically show the same data, but in a more visually way.
are histograms related to stem-and-leaf plots?
They are related in the sense that both are visual representations of numerical data. More than that, stem-and-leaf plots are most useful when the sample size is small. The plot produced may approximate to a histogram that would be produced if more data were available. When a larger sample is available it is customary to sort the sample and then split it up into about seven groups such that the middle groups are of about equal width, and then count the number of items in each group to make a histogram. As you will discern, the two processes, one of producing a stem-and-leaf plot and the other of producing a histogram will produce more or less the same result, given a sufficiently large sample.
Which is more useful specific data or general data?
It would depend on what it was used for, an overall view or something more detailed
How can a graph of data be more information than a table of the same data?
It does not. In fact, it usually contains less information because some of the precision of the data in the table may not be easy to retrieve from the graph. However, many people (but not all) find it easier to get a summarised version of the information from a graph than from a table.
When reading a table a comment located just below the title that gives more detailed information on how the data was collected or how the data are presented is called a?
