This image displays an active classroom setting in Uturu, Nigeria. A female individual, viewed from behind and slightly to the left, is standing at a white dry-erase board and actively writing on its surface. She has long, dark, curly hair and is wearing a red long-sleeved top and a black and white patterned skirt. The whiteboard contains handwritten educational content, including the title "MEDIAN," the course code "GH 305," mathematical formulas for calculating median (e.g., "[n/2]th", "[(n+1)/2]th") for "even data set" and "odd data set," and numerical examples such as "35[7]89." The whiteboard is mounted on a light yellow wall, which exhibits minor scuffs and marks. In the immediate foreground, the backs of at least four seated individuals, presumably male students, are visible, facing the whiteboard. Their clothing includes various dark-colored shirts; one student on the far right is wearing a grey cap. The scene depicts an ongoing educational lesson.
