Questions 6-9. Consider the data in the table. Absolute Relative Percent |Change Change Increase Time Value 13.60 17.00 2 21.25 3 26.56 |4 33.20 41.50 Which model would better represent this data, linear or exponential? Why? An exponential model would be better because the relative change is constant. A linear model would be better because the relative change is constant. A linear model would be better because the absolute change varies. An exponential model would be better because the absolute change is constant.
TIMELINE OR LINE GRAPH The Timeline Graphs necessary for this exercise are also in Public Files/Mod1 A timeline or line graph shows trends over time. This study examines whether there is any relationship between the season of the year and suicide rates. These two line graphs show rates per 100,000.This study was based on data from Hong Kong only for the years 1980 to 1994. Line Graph images 1.5 1.0 Figure 1.
