According to Article 1 of the Constitution, how many representatives there are in Congress is determined by each state's population. A census is taken every 10 years to accurately apportion a state's representatives. The most basic calculation is there is to be one representative for every 30,000 residents. If there are not 30,000 people living in a state, that state will still get at least one representative.
Find the Class Width of the Frequency Table. The lower limit for every class is the smallest value in that class. On the other hand, the upper limit for every class is the greatest value in that class. The class width is the difference between the upper or lower class limits of consecutive classes. All classes should have the same class width. In this case, class width equals to the difference between the lower limits of the first two classes. Simplify to find that the class width is .
If the middle number lies between two numbers, find the mean of those two numbers (add them together and divide by 2). The mode is probably the least common way of finding the average, and in most cases is the least useful. To find the mode, just look for the number that occurs the most.There can be more than one mode, or none at all. Finally there is the range. The range is NOT a measure of the average; however, it is often taught along with averages because it's another helpful way to measure a set of data.The range measures the spread of the data, how far apart the smallest and largest values are.To find the range, subtract the smallest value in the data set from the largest. This will all make a lot more sense with some real examples.For our social networking survey, we found the mean, median, and range for the amount of time each group spends on social networking sites per day.f the middle number lies between two numbers, find the mean of those two numbers (add them together and divide by 2). The mode is probably the least common way of finding the average, and in most cases is the least useful. To find the mode, just look for the number that occurs the most.
