2. Load tidyverse, read in the data, and summarize, with 1-3 sentences explaining the summary statistics.
3. What are the most popular boy and girl names over the entire period of the dataset? How many babies
were given these names between 1940 and 2022? Explain in 1-2 sentences.
4. In cultures with more nonconformity, parents may be more likely to choose uncommon names, leading
to a greater number of names. How has the number of unique boy names and unique girl names changed
over time in the United States? For each sex separately, plot the number of unique names over time in
a graph. Interpret the graph in 2-3 sentences.
5. Changes in the number of unique names may reflect changes in the number of babies rather than changes
in conformity among parents. Redo the graph from question 3 to address this issue. For each sex and
year, calculate the ratio of the number of unique names to the total number of babies. For each sex,
plot the ratio over time in a graph. Did the number of unique names rise faster than the number of
babies? Are the patterns consistent with increasing or decreasing conformity? Explain in 2-3 sentences.
6. Choose 1-3 names that interest you. State the names and explain why you chose them in 1-2 sentences.
7. Combining across all years, how common are your chosen names relative to the most popular names
you found in question 3? Explain in 1-2 sentences.
8. Plot the time series of frequencies for all 1-3 names in one graph. Interpret your results in 3-4 sentences.
