Final answer:
To estimate the first quartile, median, and third quartile from a histogram, analyze the shape and distribution of the data and approximate the locations where the lower and upper halves of the data fall.
Step-by-step explanation:
To estimate q1, the median, and q3 from the histogram, we need to analyze the shape and distribution of the data. The first quartile (q1) represents the middle value of the lower half of the data, while the third quartile (q3) represents the middle value of the upper half. The median represents the exact middle value of the data. To estimate these values, we can look for approximate locations on the histogram where the lower 25%, 50%, and 75% of the data fall.
