ملخص الدرس

This lesson covers how to estimate the arithmetic mean, median, and mode from a frequency table with intervals. It explains the method for calculating the mean using the midpoint of each interval, and how to find the median and mode using the ogive and histogram, respectively. The lesson emphasizes interpreting these measures to describe the center of the data.

هتتعلم إيه فى الدرس ده

• The arithmetic mean for grouped data is estimated using the midpoint of each interval: mean = Σ(f * x_m) / Σf.
• The median is estimated from the cumulative frequency curve (ogive) by locating the (n/2)th value.
• The mode is estimated from the histogram by identifying the modal interval and using interpolation.
• These measures help summarize and describe the central tendency of the data.
