## 4 Results of Surveys
All the obtained responses, properly grouped, are presented in Figure 4.  
Statistical significance was analyzed for various groups of people in terms of sex and age group. Due to the small number of responses in the group of respondents aged over 70, their results were combined with the group aged 50-70. The statistical analysis was performed with the Kolmogorov-Smirnov lambda test. The distribution of the obtained responses in individual groups of people was compared, at the alpha significance level of 5%. With such selected assumptions, it turns out that:  
1. there are significant statistical differences in the way of using a mobile phone between women and men;
2. there are no significant statistical differences in the way of using a mobile phone between the age group of 18-24 and 25-50, but there are significant differences between these groups compared to the oldest group of people (over 50);
3. there are significant statistical differences in the reasons for the use of a mobile phone by drivers between men and women and between the youngest group of people (aged 18-24) and the rest, but there are no significant statistical differences between the group of people aged 25-50 and over 50 years of age;
4. there are significant statistical differences in the reasons for the use of a mobile phone by passengers for travel between all groups of people, broken down by gender and age;
5. there are significant statistical differences in the reasons for using a mobile phone at once after stopping at a red-light signal interval between all surveyed groups of people, except for the groups of people aged 25-50 and over 50. The main difference between men and women in the manner of use mobile devices is that men more often use a mobile phone attached to a special holder, and women more often use a mobile phone in their hand. In the case of the reasons for using a mobile phone when the driver is a woman, the main difference compared to men is primarily a much smaller percentage of women who change music and look for information via a mobile

In the case where a woman is a passenger, the main difference is the much greater share of using a mobile phone to look at the status of other social profiles and to read mobile media content in relation to male passengers. Men, as passengers, play more on their mobile phones. In the case of differences between a woman and a man who wait for a green signal in the car, more men change the music on the mobile phone than women, and women more often continue or start a voice call on the mobile phone than men. In the case of differences noted in individual age groups of respondents, young drivers using a mobile phone while traveling much more often reply to or start a new text message and change the music using a mobile phone more often. However, what is quite surprising is that they continue or start a voice call using a mobile phone less frequently than older drivers. In the case of differences noted in individual age groups of respondents, young drivers using a mobile phone while traveling much more often reply to or start a new text message and change the music using a mobile phone more often. However, what is quite surprising, they continue or start a voice call using a mobile phone from older drivers less frequently. In individual age groups, people who are passengers behave in a statistically significant, different way from each other. The main differences result from the frequency of voice calls, replying to SMS messages, looking at social media profile, and playing and changing music. In individual groups of people in terms of their age, only young drivers, compared to the older and the oldest ones, use the mobile phone differently while waiting for the green signal. The main differences are:  
* more frequent texting,
* less frequent voice calls,
* definitely more frequent changes of music.
