The presented histogram illustrates the range of responses for the question about the importance of full color vision given by color blind and not color blind people. At first, we can notice that the variance of the responses is quite similar in general for each group of the people. Another observation is the number of respondents who chose 7 - 8 points out of 10 of the necessity scale is stand out of the trend. Let’s give a closer look at the graph. 25% of not color blind respondents, which is the highest number among them, thought that the full color vision is almost necessary – they marked it with the 8 out of 10 points. Another group - around 20% color blind respondents, which is the highest number among them, thought that full color vision is completely necessary. The number of respondents in each group with the opinion that the full color vision isn’t necessary at all is less than 5%. In summary, we can make the following conclusion. In general, each group of the peopl...
The chart above presents the number of transport usage by each type in 2004 and 2014. In 2004, the most popular type of transport was a car with the percentage at 75, other types of transport including “didn’t travel” option weren’t so popular, and their proportion ranged from 0.1 to 7.6 percent. Over ten years, car transport with the percentage at 65.5 remained as the most popular type, the proportion of other types of transport varied from 0.1 to 8.0 percent. Although, a closer look at the table reveals that the number of car usage decreased in favor of ‘’walk” and “bicycle” options. So, if car transport usage dropped by around 9 percentage points, the number of ‘’walk” and “bicycle” options increased for the same amount, from 3.9 to 8.0 and from 1.2 to 6.5 respectively. Over a decade we see that the car is still popular and most common type of transport. At the same, time the number of alternatives to car - ‘’walk” and “bicycle” increased with the falling number o...
