澳洲邦德大学代写论文：气候对交通工具的影响
归一化温度范围为0.06 ~ 0.86，即温度范围为2.42 ~ 35.33oC。归一化温度范围为0.08 ~ 0.84，相当于3.95 ~ 42.04摄氏度。湿度在0 ~ 97.25%之间，风速在0.02 ~ 0.51之间。因此，实际风速在1.50至34.00之间。每天在路上行驶的自行车数量从22辆到8714辆不等。

表2给出了上述一组变量的相关分析。表2所示的相关系数均具有统计学意义，p值<0.01(表6)。自然条件对应的变量之间均存在相关性，可能存在多重共线性问题。自行车数量与环境温度和感觉温度呈正相关。考虑到温度范围在2.42 – 35.33摄氏度之间，感觉温度范围在3.95 – 42.04摄氏度之间，正相关说明人们并不介意在较高的温度下骑自行车，但在较冷的环境下骑自行车更敏感。湿度和风速之间的负相关关系是可以理解的，因为众所周知，在气候条件下，人们更喜欢汽车而不是自行车。

The normalized temperature ranges from 0.06 to 0.86 which translates into a temperature range of 2.42oC to 35.33oC. The normalized feeling temperature ranges from 0.08 to 0.84 which is equivalent to a range of 3.95oC to 42.04oC. The humidity ranges from 0 to 97.25% whereas the normalized wind speed ranges from 0.02 to 0.51. The actual wind speed thus ranges from 1.50 to 34.00. The number of bikes travelling through the roads on a given day ranges from 22 to 8714.

Table 2 presents the correlation analysis of the above set of variables. All the correlations shown in table 2 are statistically significant with p-values <0.01 (table 6). The variables corresponding to natural conditions are all correlated to each other which can lead to the potential problem of multicollinearity. The correlation between number of bikes and both ambient temperature and feeling temperature is positive. Given that the range of temperature is 2.42oC to 35.33oC and the range of feeling temperature is 3.95oC to 42.04oC, the positive correlation implies that people do not mind using bikes in hotter temperature but they are more sensitive to using bikes in cold. The negative correlation between humidity and wind-speed is understandable as they are known climatic conditions during which people prefer cars over bikes.
