Math Problem Statement

Please answer the following questions: 1. Complete the data and construct a frequency polygon and histogram for the given data. 2. Find the value of mean (short-cut and step deviation method), mode, and median from the data.

Solution

It seems that you've uploaded an image with a table containing frequency data for different intervals and two tasks:

  1. Completing the data: This requires filling in the frequencies for the intervals 40-50 and 80-90, where the frequencies are represented by variables XX and YY. Since these variables are linked to specific personal data (last two digits of your Class ID and your date of birth), you'll need to provide those numbers for me to complete the table accurately.

  2. Calculating statistical measures:

    • Frequency polygon and histogram
    • Mean: Using the shortcut method
    • Mode: The value that appears most frequently
    • Median: The middle value when the data are arranged in order

For now, please provide the values for XX and YY or any other specific numbers needed to fill in the missing data. If you want, I can also guide you on how to construct the frequency polygon and histogram or calculate the mean, mode, and median with the complete data.

Would you like to proceed with filling in the values for XX and YY, or would you prefer help with another part of the question?

Formulas

Mean (Shortcut method): \( \bar{x} = A + \frac{\sum f_i d_i}{\sum f_i} \)
Mode: \( Mode = L + \frac{(f_1 - f_0)}{2f_1 - f_0 - f_2} \times h \)
Median: \( Median = L + \frac{\frac{N}{2} - F}{f} \times h \)
