Histogram equalization accomplishes this by spreading out the most frequent intensity values effectively. Do most programmers/software engineers are usually the quiet type? (although it may be a large number.) In our example 280 grams would represent the 69th percentile for apples since 69% of apples have weights lower than 280 grams. Line graphs are used to represent quantitative data collected over a specific subject and a specific time interval.

Disadvantages: There are a few methods can used in formulating class intervals: "from 5-10" or "Over 55" & "less than 30". Advantages: Work well for displaying large ranges of data or information; Intervals are always equal, allowing for consistency with data; Easy to transform data from frequency forms to graph forms; Disadvantages: Impossible to extract an exact amount for input; Inability to compare multiple points of data in one chart; Stem and Leaf Plots disadvantages: - difficult to compare the frequencies between each data group.

Cumulative impact simply means changes in system or project that are caused due to combined impact of past, present, and future activities or natural processes of human beings. Circle graphs. The advantages of oscillators is that they have good stability at high frequency and have a good wave purity. The cumulative frequency for the highest score in a data set is equal to the sum of frequencies, since all scores fall at the highest score or lower. The cumulative record, used in operant experiments, is a graphic record which emphasizes the rate of performance or its frequency.
