The amount of clusters must be determined [35]. An appropriate quantity of subgroups was determined according to a cutoff worth of 15 along with the biggest distance between clusters (vertical lines) within the dendrogram [37] (Figure 1). K-means clustering, which permits the researcher to pick the acceptable quantity of clusters for the evaluation, was performed making use of Ward’s process to partition the dataset into appropriate subgroups, e.g., [25,35]. The maximum iterations were adjusted from ten to 99 to avoid any difficulties with early convergence in the resolution. Convergence was achieved in 12 iterations. Soon after person circumstances were assigned for the two clusters, analysis of variance (ANOVA) was made use of to determine the magnitude of difference between the variables of interest and cluster membership. Chisquare analyses were utilised to identify significant differences in between the cluster groups’ categorical demographics (e.g., age, sex, education, household earnings, and political ideology)., 13, x FOR PEER REVIEW7 PK 11195 manufacturer ofWater 2021, 13,7 ofthe cluster groups’ categorical demographics (e.g., age, sex, education, family income, and political ideology).Figure 1.

LimitationsUsing non-probability opt-in sampling have to be acknowledged as a limitation. While public opinion analysis generally makes use of non-probability opt-in sampling [31], the sample Utilizing non-probability opt-in sampling has to be acknowledged as a limitation. Altmay have bias, as not all sorts of individuals have access for the world-wide-web and not all sorts hough public opinion research generally utilizes non-probability opt-in sampling [31], the samof people will answer surveys [32]. Additionally, the survey focused on water and ple might have bias, as not all types of men and women have access for the internet and not all respondents may have felt pressured to conform to their perceived norm about water forms of men and women will answer surveys [32]. In addition, the survey focused on water and conservation [39]. respondents might have felt pressured to conform to their perceived norm about water conData were collected throughout a politically contentious time period within the U.S. [40], possiservation [39]. bly altering respondents’ political viewpoints in the brief term. For example, a partisan divide within the U.S. public was triggered by the 2020 Presidential Election, with the Republican incumbent obtaining the biggest partisan gap in approval rating identified from polling2.5. LimitationsWater 2021, 13,8 ofdata [41]. Furthermore, the death of George Floyd, a Black man who was killed in police custody in Minneapolis, sparked protests around the country [42]. The U.S. public was divided in their opinions of what brought on the protests, with 45 of Republicans and 84 of Democrats believing the protests had been on account of deep-rooted mistreatment of Black people today inside the country [42]. Yet another limitation was that information were collected through the coronavirus pandemic, which may have influenced how respondents participated within the survey. For example, the coronavirus pandemic caused quite a few public spaces, which include libraries and net cafes, to UCB-5307 Autophagy temporarily close and only residents with web access had the ability to participate in the online survey [43,44]. Additionally, the coronavirus pandemic enhanced consumers’ engagement with nature (i.e., going to parks, identifying plants and animals) all through the U.S. [45], which.
