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.
What are the categories by which data are grouped?
Data can be grouped or ungrouped. The categories data are grouped in depend on the data. For example, data collected about people could be grouped as male/female, by ages, or some other common characteristic. Data collected about dogs could be grouped by breed of dog, age, long hair/short hair, or size.

What type of graph would be needed for a mode calculation?
For discrete data, a bar chart. For continuous data a grouped frequency chart (histogram).
When should measures of location and dispersion be computed from grouped data rather than from individual data values?
The main need to work with grouped data was to reduce the number of data points that need to be stored and processed in calculation. With modern computers the storage and computation are not likely to be issues in many situations and so there is no need to use grouped data.
Is this a true statement An analog signal consists of individual electrical pulses that represent bits grouped together into bytes?
no. The answer is digital signal.
