Line graph - flue rates for males and females
Death from Flue
Risk level among females who were vaccinated

Model Answer 1: 
The illustration outlines the outcome of a flu vaccine trial among females in a big town in June 1996. Overall, the experimental flu vaccine was not effective in terms of its result on females.

The diagrams reveal that flue rate was generally higher among women than that of men in 1996. From April 1996 to June 1996, the infected people’s number increased swiftly and more female became vulnerable to the flu than that of men. At the beginning of June, the number of male patients was somewhat 2500 compared to 3500 females at which point the injection was tested among women. Though it might seem that the flu contamination among female decreased afterwards, the overall flu rate among males gives a different scenario. During August until the end of the year, around 2500 females were recorded to have flue while this number was a thousand fewer for males.

Interestingly, only 1 female died from flu during March to May 1996, but after the vaccination, the death case rose – 4 female and 2 male death cases were recorded between June and August.

Finally, almost a quarter of female child and 35% elder females were at risk despite the immunization. 13% needed medical attention while just over a quarter who did not receive the injection were also at risk.
Sample Answer 2:  
The diagrams present results of a survey conducted in a big municipality on the flu vaccine to women in June 1996. Generally speaking, more females were affected by the flu than men did and death rate among women from the flu was also higher.

As the data suggests, from February to June, the number of flu infection steadily increased. More females were affected by flue than men did and in the middle of the year, this infection spread among more than 3500 female and more than 2500 men at which point the injection experimented. The infection rate in the rest of the year remained constant – 2500 females and 1500 males.

The bar graph shows the death cases from the flu and it is obvious that female death case was higher than the male mortality event. From June to August, 2 men died from the flu infection where 4 women departed from the same flu.

Finally, the pie chart presents data on the aftermath of the vaccination. It can be observed that older women and children were at more risk than other age groups of females.
