## Numerical Summaries

To understand the data, we first compute the following numerical summaries:
- Mean and median temperature anomalies for global, Northern Hemisphere, and Southern Hemisphere datasets.
- Standard deviation and range of temperature anomalies to measure variability.

```{r}
# Load data
global_data <- read_csv("GLB.Ts+dSST (1).csv", skip = 1, na = "*")
northern_data <- read_csv("NH.Ts+dSST.csv", skip = 1, na = "*")
southern_data <- read_csv("SH.Ts+dSST.csv", skip = 1, na = "*")
zonal_data <- read_csv("ZonAnn.Ts+dSST.csv", skip = 1, na = "*")

Giving you csv files to understand the data to do the above things This data is from NASA
