# Temporal Variations Dataset for Indoor Environmental Parameters in Northern Saudi Arabia
## 4 Dataset Description
### Summary Statistics  
Here, the dataset statistics summary is measured using the count, min and max, and percentiles, Table 9. They are defined as follows:  
* Count: The number of data points in the dataset;
* Minimum and Maximum: The smallest and largest values in the dataset;
* Percentiles: The values below which a given percentage of the data falls. Common percentiles are the 25 th, 50 th (median), and 75 th percentiles.  
The data in Table 9 includes various statistical measures for five metrics: light, temperature, humidity, pressure, and attitude. The measures given are count, minimum, maximum, 25 th percentile (1 st quartile), median (50 th percentile or 2 nd quartile), and 75 th percentile (3 rd quartile).  
Light: The light intensity ranged from 0 to 856 units, with half of the readings below 102 units (the median). The 25 th percentile and minimum are both 0, meaning at least 25% of the readings were 0, aligning with the previous observation that the most frequent light reading is 0. The 75 th percentile is 565 units, indicating that 25% of the readings were above this level.

Table 9: Statistics Summary.  
Temperature: The temperature values ranged from 29.3 to 40.2, with a median of 37.1. The interquartile range (IQR), which ranges between the 25 th and 75 th percentiles, is from 36.2 to 38.1, meaning that 50% of the temperature readings fall within this range.  
Humidity: Humidity varied between 10 and 25 units. The median and the 25 th percentile are 11, and the 75 th percentile is 12, indicating a concentration of values around the lower end of the range and potential skewness to the right.  
Pressure: The pressure ranged from 88,982 to 89,882 units, with a median of 89,455. The IQR spans from 89,355.25 to 89,542, showing that the middle 50% of pressure readings are relatively tightly clustered in this range.  
Attitude: Attitude values extended from 999.59 to 1082.21 units, with a median of 1038.56. The IQR is from 1030.55 to 1047.77, indicating that 50% of the attitude measurements are within this range.  
The 'count' row confirms that there are 8910 data points for each measure, ensuring that comparisons between the measures are valid.
