An anthropologist is comparing household storytelling frequencies across three indigenous groups. Group A tells 5 stories per week, Group B tells 8 per week, and Group C tells 3 per week. If she observes 15 households from A (average 4 members each), 10 from B (average 5 members each), and 20 from C (average 3 members each), what is the average number of stories per person per week across all observed individuals?

["Understanding Household Storytelling: A Cultural Comparison Across Three Indigenous Groups", "Storytelling is a cornerstone of cultural identity and knowledge transmission, especially among indigenous communities. Anthropologists studying oral traditions often analyze how frequently storytelling occurs within households and how that compares across different groups. Based on recent fieldwork, a researcher compared storytelling frequencies among three indigenous groups—Group A, Group B, and Group C—revealing significant differences in weekly narrative practices. This article explores the data, calculating the average number of stories per person per week across all observed individuals to shed light on cultural patterns in oral storytelling.", "### The Observation Framework", "The anthropologist systematically observed households across three groups to gather robust data. The sampling was structured as follows:", "- Group A: 15 households, each with an average of 4 members\n- Group B: 10 households, each with an average of 5 members\n- Group C: 20 households, each with an average of 3 members", "The storytelling frequencies are similarly distinct:\n- Group A tells 5 stories per household per week\n- Group B tells 8 stories per household per week\n- Group C tells 3 stories per household per week", "### Calculating Total Weekly Storytelling", "To find the total number of stories shared weekly across all observed individuals, we compute:", "- Group A:\n $ 15 \ ext{ households} \ imes 4 \ ext{ members/household} \ imes 5 \ ext{ stories/household} = 300 \ ext{ stories/week} $", "- Group B:\n $ 10 \ ext{ households} \ imes 5 \ ext{ members/household} \ imes 8 \ ext{ stories/household} = 400 \ ext{ stories/week} $", "- Group C:\n $ 20 \ ext{ households} \ imes 3 \ ext{ members/household} \ imes 3 \ ext{ stories/household} = 180 \ ext{ stories/week} $", "Adding these together gives the total weekly storytelling across all households:\n$ 300 + 400 + 180 = 880 \ ext{ stories/week} $", "### Counting The Total Number of Observation Participants", "Next, we calculate the total number of individuals observed:\n- Group A: $ 15 \ imes 4 = 60 $\n- Group B: $ 10 \ imes 5 = 50 $\n- Group C: $ 20 \ imes 3 = 60 $\nTotal observed individuals: $ 60 + 50 + 60 = 170 $", "### Computing the Overall Average Stories Per Person Per Week", "The average number of stories per person per week is found by dividing total stories by total individuals:\n$ \frac{880}{170} \approx 5.18 \ ext{ stories/person/week} $", "---", "Conclusion\nAcross the three indigenous groups, the anthropologist’s observations reveal an average of approximately 5.18 stories per person per week when accounting for household size and storytelling frequency. Group B leads in storytelling intensity, while Group C maintains a more modest narrative output—yet all contribute to the rich oral traditions that define each community’s heritage. This quantitative insight enhances cross-cultural understanding and underscores storytelling as a vital, measurable element of human connection."]
