Math Problem Statement
the following data shows the number of children in a survey of 15 families. number of children : 2, 1, 3, 2, 1, 2, 3, 4, 2, 5, 1, 2, 4, 1, 6. Use the information to draw a dot plot showing this data
Solution
as plt
Data
number_of_children = [2, 1, 3, 2, 1, 2, 3, 4, 2, 5, 1, 2, 4, 1, 6]
Create the dot plot
plt.figure(figsize=(10, 5)) plt.scatter(number_of_children, [1] * len(number_of_children), alpha=0.7, color='blue', s=100) plt.title('Dot Plot of Number of Children in 15 Families', fontsize=14) plt.xlabel('Number of Children', fontsize=12) plt.xticks(range(1, 7)) # Showing tick marks for all possible numbers of children plt.yticks([]) # Remove y-axis as it's not needed in a dot plot plt.grid(axis='x', linestyle='--', alpha=0.5) plt.tight_layout() pltThe dot plot above displays the number of children in each family from the given data. Each dot represents a family.
Would you like further clarification or analysis based on this data? Here are some related questions to explore:
- What is the mean number of children per family in this survey?
- How does the mode of the data compare to other measures of central tendency?
- Can we identify the range of the number of children in these families?
- How would a frequency distribution table look for this data?
- Could this data be visualized using other types of plots, such as a histogram?
Tip: Dot plots are particularly useful for visualizing small data sets and identifying clusters
