Problem 2:

Given the following data:

1. Calculate the Median for frequency distributions with grouped classes using the following formula,
   \(\text { Median }=\text { L.R.l. }+\left[\frac{\mathrm{n} / 2-\mathrm{fa}}{\mathrm{f}}\right] \text { (i) }\)
2. Calculate the Standard Deviation using the following formula,
   \(s=\sqrt{\frac{\sum X_{i}^{2} f-\left[\left(\sum X_{i} f\right)^{2}\right] / n}{n-1}}\)
3. Calculate the Variance

3. Given the following data:

Using 8 classes or intervals,

1. Construct the Frequency Distribution Table (include the relative frequency).
2. Construct the Histogram (Use the Relative Frequency in the vertical axis).
3. Construct the Frequency Polygon.
4. Calculate the Mean for frequency distributions with grouped classes using the following formula,
   \(\bar{X}=\frac{\sum X_{i} f}{n}\)
5. Calculate the Mode.
6. Calculate the Median for frequency distributions with grouped classes using the following formula,
   \(\text { Median }=L_{.} \text {R.I. }+\left[\frac{n / 2-f a}{f}\right] \text { (i) }\)
7. Calculate the Standard Deviation using the following formula,
   \(s=\sqrt{\frac{\sum(X-\bar{X})^{2} f}{n-1}}\)
8. Calculate the Variance

4. The math class took the final exam. The following are the grades that the students received on the test: 64,71,73,78,79, 81, 81, 83,83,83,85,85,86,88, 93,95,97,97,99,100

Using this data;

1. Calculate the Quartiles.
2. Calculate the Interquartile Range
3. Calculate the Semi-interquartile Range
