I need to analyze correlations between columns in this Olympic table tennis dataset. Let me examine the relationships between different variables. {"action": "tool_call", "reasoning": "First, I'll compute correlations between the numeric columns (year, is_china, medal_value) to see if there are any strong linear relationships.", "tool": "query_sql", "args": {"sql": "SELECT CORR(year, medal_value) as year_medal_corr, CORR(year, is_china) as year_china_corr, CORR(medal_value, is_china) as medal_china_corr FROM raw.olympic_table_tennis_medals_1988_2024", "purpose": "Calculate Pearson correlations between numeric columns", "source": "raw"}}
