lengthen: The dataset provides descriptive statistics for two variables: obesity and heart attack occurrence among a sample of 400 individuals. For the obesity variable, out of 400 respondents, 279 individuals (69.8%) were classified as obese, while 121 individuals (30.3%) were not. The mean for obesity is 1.70, with a median and mode of 2, indicating that the majority are classified as "Yes" (coded as 2). The standard deviation is 0.460, showing a moderate spread in the data. Regarding heart attack occurrences, only 17 individuals (4.3%) reported having had a heart attack, whereas 383 (95.8%) did not. The mean for heart attack occurrences is 1.96, with both the median and mode being 2, suggesting most participants did not experience a heart attack. The standard deviation of 0.202 indicates less variability in heart attack data compared to obesity. Overall, this descriptive analysis reveals that while a significant portion of the sample is obese, the occurrence of heart attacks is relatively low
