The combined bar graph illustrates the population of learners who selected three different subjects;biology, maths and history in an institution between 2010 and 2020 .
In general, more learners chose maths over years in contrast with history where few learners chose history. Biology showed fluctuation in number of learners.
To begin with,history recorded the lowest population at approximately 90,100,110,115,120,125 in 2010,2012,2014,2016,2018 and 2020 respectively. In contrary mathematics recorde more number of learners with 2020 having highest number at around 220 and also lowest number at about 80 learners. However over years mathematics showed evidently an increase in number of learners from 125 ,150,155,155 to 170 from 2010 upto 2018.
However, biology showed fluctuations in numbers.But from 2010 to 2016 there are double bars of biology where in 2010 110 and 120 learners selected biology while in 2012 about 145 and 155 learners selected biology. Less number is seen in 2014 at 135 and 145.However in 2016 high number is recorded at 200 and 145 the same year. In 2018 145 learners chose biology while in 2020 155 number was recorded.
