500 WORD EXAPLAIN THIS GRAPH IN THIS Contents Introduction 3 Explanation of the graph 3 Conclusion 5 Reference 6 Introduction In this assignmenta graph has been drawn and the following discussion will be focused on describing the characteristics of that graph. Explanation of the graph The title of the graph is time management concept in EBSCO database by Decade. In the following graph a time period has been considered ranging from 1911 to 2010. The entire data range has been divided into 10 class intervals of equal range.

The difference between the upper class interval and the lower class interval is 9. There the data set consist of 10 intervals. The first ranges being 1911 to 1920 while the last range being 2001 to 2010. The horizontal axis of the graph depicts the years under consideration while the vertical axis depicts the time management data. Since the results were “zero” for the first set of data it can be seen in the graph that the curve starts from the point “zero”. In accordance with time the results varied and therefore the shape of the curve varied as well.

The initial part of the curve is elongated mainly because the data for those years are very small and therefore the curve for those years never really got the push to rise. The horizontal curve starts from the range of 1911 to 1920 as stated in the data set. Each of the data sets i.e. the class intervals has been taken as points on the horizontal curve and accordingly the curve in drawn in excel taking each result of the data under consideration. The excel puts the results corresponding to each class interval and the curve is drawn accordingly.

It can be seen that the curve becomes steep rising after the class interval of 1981 to 1990. For the class interval of 1991 to 2000 and for the class interval of 2001 to 2010 the curve is on the rise. The vertical curve points to the results as stated in the data set. The difference between points on the vertical axis is 1000. When the data set is put into excel. The graph will automatically take the default ranges of the vertical and also for the horizontal axis. The data labels on the curve imply the results on the data set considered.

It can seen that each and every point on the data set and on the curve is matching which proves the correctness of the graph. It can also be implied from the curve that the time management concept was more popular after the years of 1990 as the graph becomes steep rising after that point. YEARS RESULTS 1911-1920 0 1921-1930 1 1931-1940 3 1941-1950 2 1951-1960 23 1961-1970 90 1971-1980 231 1981-1990 456 1991-2000 2071 2001-2010 4847 The graph drawn with the above data is as follows: Conclusion Conclusively it can be stated that the curve provides a rough idea about the popularity of the time management concepts for the ten periods considered in the data set.
