Rhe general information Essays

Rhe general information Essays Rhe general information Essay Rhe general information Essay Average age of the passengers of TITANIC was 29.88 years old. Considering the fact that 25% of the passengers were younger than 21 (1st quartile) and only 25% of passengers were older than 39 (100% the 3rd quartile), half of the passengers age was between 21 and 39 (3rd quartile 1st quartile), which indicates that the population of TITANIC was quite young.  The range of the age was pretty wide (79.833), since the youngest baby was 0.167 and the oldest was 80. Therefore, even though the majority of passengers were young, each category of ages from 0 to 80 had some representatives.  General equilibrium of the age (mean) is greater than the median, which means that the whole tendency of the age goes rightward, resulting in positive skewness (rightward skewed distribution). As we can see in bar chart below, there is a high frequency in ages 20 and 30, resulting in an asymmetry distribution. Age 80 in this case is an outlier; its value is too high with respect to the other ages. There was only one person who was 80, out of 1309 passengers. The kurtosis index is low (0.14) suggesting a hypo-normal (more flat) distribution relative to a normal distribution. In other words, the data have a flat top near the mean rather than a sharp peak.  1.2. Gender  The data inferred that there were more males than females on TITANIC. More than half of the population of TITANIC was male compared to only about 40% of the passengers who were female. The minimum ticket price was 0 which means that some passengers did not pay anything for the trip. Average ticket price was about 33 dollars which is quite low considering the most expensive fare was 512 dollars. That is because 75% of the passengers (3rd quartile) bought the ticket below the price of 31.27 dollars, 25% of them (the rest) paid from 32 dollars to 512 dollars. One of the main reasons the mean is not an appropriate measure is its sensitivity to extreme values. This is certainly the case with our data which comprises some extreme prices. Therefore, we can see the outlier (512) in the box plot which is way higher compared to the mean of the ticket fare. This means that a very select clientele paid extremely much, perhaps being offered the appropriate luxury. Additionally the distribution is asymmetric, rightward (positive) skewed because the mean is greater than the median; general equilibrium is much higher the middle number. Upper limit is quite wide since, 3rd quartile is high, respectively 1st quartile is only 7 dollars. As we can see in Histogram above, the majority of the passengers bought their ticket under the 50 dollars threshold. Between 32 dollars and 512 dollars ticket, many of them sold by price about 200-250 dollars. In fact only 4 people got the 512 dollar ticket out of 1309 passengers. As a result, most of the passengers on TITANIC had comparatively cheap tickets, even though a select few enjoyed the luxury travel that an expensive ticket bought them. Below, heres a more representative Histogram of fares, one in which we have purposely omitted these luxury ticket prices, and we have increased the number of classes: We found out that there was a difference in the prices of those who survived, namely they paid more for their tickets. However, we cannot infer that survival depended on the ticket price because of the high variability of those who survived. The maximum price paid by a survivor was 512 while the maximum paid by a non-survivor was 263. This doesnt tell us much except that all 4 people who paid the extreme amount of 512 survived.  On average, the survivors paid more than double for their prices but again, the average was influenced heavily by the outliers. Conclusion By making a simple analysis of the general information of TITANIC, we were able to describe the population of the ship in terms of several variables. To summarize, the population was relatively young, more than half of them were males who did not pay too much for their tickets. This fits with the stereotype of the poor young man, in his 20s, looking for a new life in the land of the dreams. Unfortunately, survival ratio from TITANIC was not very high, only slightly less than 40% of the passengers were able to further pursue their dreams.
