Math Problem Statement
Solution
The table provided in the image is a frequency distribution of student scores in a particular exam. The columns appear to indicate:
- Score Range (درجات) - The ranges of scores obtained by students.
- Frequency (عدد الطلاب) - The number of students who scored within each range.
Here’s a summary of the table as observed:
Score Range | Frequency |
---|---|
90 - 99 | 4 |
80 - 89 | 6 |
70 - 79 | 17 |
60 - 69 | 17 |
50 - 59 | 10 |
40 - 49 | 6 |
This data likely requires the calculation of the mean, median, or mode to find the average performance or other statistics, depending on the specific requirements.
Would you like me to calculate any statistical measures, such as the mean, median, or standard deviation, based on this data?
Here are some follow-up questions that may expand your understanding:
- What is the purpose of this data set, and are you interested in specific calculations like mean or median?
- Are there any missing details or additional data you'd like to add?
- Would you like a histogram or other visual representation of this distribution?
- Do you want to calculate the cumulative frequency for each score range?
- Should I calculate the weighted average based on this data?
Tip: Frequency distribution tables are very useful for understanding the spread of data quickly and are a great starting point for various statistical analyses, such as finding trends or typical values.

Formulas
Mean = Σ(frequency * midpoint) / Σ(frequency)
Median = L + [(N/2 - cumulative frequency) / frequency] * class width
Mode = L + [(frequency of mode class - frequency of previous class) / (2 * frequency of mode class - frequency of previous class - frequency of next class)] * class width
