### Box and Whisker Chart Analysis Results for Proenvironmental Behavior Practices  
The revealed differences were analyzed by constructing box and whisker diagrams, reflecting the median, and quartiles of 25%-75% and the maximum and minimum values of each group's respondents' ratings. Differences due to the discrepancy between only the quartiles of 25-75% and the discrepancy between the median estimates of only groups 4, 5, and 6 (the smallest, cannot be generated randomly) were excluded from the meaningful interpretation. In those cases, when the median values of the most numerous groups of respondents (1, 2, and 3) differed among themselves, we attempted to analyze and substantively explain the statistically significant differences revealed. In Figures 3-16 are box and whisker diagrams with the most noticeable differences in the respondents' assessments between groups 1--Moscow, 2--Krasnodar, 3--Krasnodar region. Figure 3: Box and whisker diagrams for practices P2 (Reducing opening and closing the door of the refrigerator) and P4 (Putting hot food into the refrigerator after cooling) from the category “energy saving”. Figure 2: Most popular groups of practices. Figure 4: Box and whisker diagrams for practice P6 (Cleaning filter of the air conditioner or cleaner) and P7 (Adjusting the temperature of the air conditioner), the category “energy saving”. Figure 5: Box and whisker diagrams for practice P8 (Turning off lights in empty rooms) and P10 (Turning off the TV when people are not watching), the category “energy saving”. Figure 6: Box and whisker diagrams for practice P12 (Doing ironing collectively) and P13 (Setting a lower shower temperature), the category “energy saving”. Figure 8: Box and whisker diagrams for practice P18 (category “Water saving”) and P21 (category “Waste management”). Figure 7: Box and whisker diagrams for practice P15 (Using toothbrush cup) and P17 (Taking short showers), category— “Water saving”. Figure 9: Box and whisker diagrams for practices P22 (Following garbage rules) and P23 (Garbage separation), the category “Waste management”. Figure 11: Box and whisker diagrams by practices P28 (Using own cup), P32 (Composting kitchen garbage), from the categories “No plastic” and “Waste management”. Figure 10: Box and whisker diagrams for practices P25 (Collection and delivery of glass containers to appropriate collection points), P26 (wastepaper collection and delivery to appropriate collection points) and P27 (Collection and delivery of used batteries, light bulbs to appropriate collection points) from the category “Waste management”. Figure 2:0 Box and whisker charts by practices P41 (Buying ecomark-appliances), P42 (Choosing goods with their CO\({}_{2}\) emission in mind (carbon footprint)), from category “Shopping”. Figure 2:1 Box and whisker diagrams by practices P33 (Throwing away kitchen garbage after it has dried), P34 (Using receptacle instead of plastic bag), from the categories “No plastic” and “Waste management”. Figure 2:2 Box and whisker charts by practices P38 (Buying organic products), P39 (Buying recycled goods), from category “Shopping”. Control over opening the refrigerator (P2): in Krasnodar, this practice is used less frequently (median 2.0, which corresponds to the answer \"rarely\") than in Moscow and small towns of the Krasnodar Territory (median 3.0, which corresponds to the answer \"often\"). Cooling hot food before placing it in the refrigerator (P4): in Krasnodar and Krasnodar region it is used more often (median 4, which corresponds to the answer \"always\") than in Moscow (median--3, which corresponds to the answer \"often\") (Figure 3). Air conditioner filter cleaning (P6) is used much more frequently in Moscow (median 3, which corresponds to the answer \"often\") than in Krasnodar and Krasnodar region (median 2--\"rarely\"). Air conditioner temperature control (P7) is more often used in large cities--Moscow and Krasnodar (median 3--\"often\"), and in Krasnodar region-less often (median 2--\"rarely\") (Figure 4).
