The image captures an indoor classroom scene in the city of Unknown, Unknown, viewed from the perspective of a seated individual in the rear. In the immediate right foreground, the back of a head with short, dark hair, belonging to a person wearing a blue garment with vertical white stripes, is visible. To the left foreground, the back of another head with short, dark hair, belonging to an individual wearing a dark checkered shirt, is observed. A hand holding a brown, cylindrical object, possibly a pen or pencil, is partially visible near this individual's head. In the mid-ground, an individual, likely an instructor, with dark skin, wearing a light-brown long-sleeved garment and a patterned cap, stands facing a white board. This individual is actively writing on the whiteboard with a dark marker in their right hand. The whiteboard displays the text "CDLL 201" and "Measure of dispersion" at the top, followed by numerical and tabular data including columns labeled "Sool F", "C", and "B" with corresponding values such as "45-295", "10", "20", "29", "335", and others. A small portrait of a man is affixed to the light-beige wall directly above and slightly to the right of the whiteboard. Below the instructor, the back of a person wearing a patterned head covering is partially visible, seated at a desk. The visible environment consists of light-colored walls typical of an educational institution.
