The line graph and the table demonstrate the average price of three types of cereals and the number of them sold in England and Wales from January to August 2014.
Overall, it can be seen that all categories of cereals witnessed downward trends in the average cost, while the quantities of them being sold underwent the opposite tendency. It is also notable that wheat experienced the most considerable change and was the bestseller among the examined kinds of cereals.
Looking at the first illustration, the rates for wheat stood at approximately 160 pounds per tonne (PPT) in January, then it peaked at about 170 PPT in late April, before decreasing significantly by 50 PPT at the end of the period. Additionally, there was a fall of 20 PPT in the cost of barley and oats. The former started at nearly 140 PPT; after remaining stable at around 145 PPT between March and April, it went down gradually to under 120. Meanwhile, the latter increased slightly from 115 PPT to about 120 PPT for half of a year, reached a peak at more than 140 PPT in July before dropping to 100 PPT in the next month.
Moving on to the remaining table, there was an increase in the figures for wheat and barley, with a slight fall between April and May. The number of tonnes of wheat climbed up from 76,800 tonnes to 163,500 in the first quarter, hit a low point at 30,800 tonnes, and then bounced back to 131,700 tonnes in August. Similarly, the rates for barley stood at 21,500 tonnes in January before rising by 10,900 tonnes in March, diminishing by 21,100 tonnes by May, and increasing to 45,100 tonnes at the end of the period. On the other hand, the quantities of tonnes of oats being sold barely made any changes, staying at around 2300 over the eight-month period.
