The pie chart below shows the results of a survey of the causes of poor learning outcomes in schools in a particular country in 2011. v.1

The pie chart presents a survey result that outlines why pupils in schools poorly performed in a country in 2011. Categorically speaking, inexpert teachers and family issues were the main reasons they had wretched outcomes in learning. As the poll data suggests, unskilled masters in schools were the primary ground for young students’ inadequate performance as 35% attribution was made to unskilled teachers. The second most protuberant reason (denoted as 27%) was indicated towards the upbringing of the children which is related to the family issue. Working-class parents were attributed to influence students learning negatively as 20% poll results linked it to the bad performance of pupils in schools. Inadequate facilities and lack of revision were pointed out to cause 10 and 8 percentages of this unsatisfactory performance based on the outcomes of the survey. To summarise, unskilled educators, family issues like working parents, improper upbringing or children, insufficient facilities and lack of study and revision were the main reasons schoolgoers' learning in this country were not up to the mark.
