Sure, here are the steps to construct a relative frequency histogram and discuss the skewness of the distribution:

1. **Collect the Data**: The first step in creating a relative frequency histogram is to have a set of data. This could be anything from the number of people who visit a website each day to the heights of a group of people.

2. **Create Classes**: Divide your data into classes (or bins). The number of classes can be determined by the Sturges' rule, which is k = 1 + 3.3 log n (where n is the number of data points). Each class should have a lower limit and an upper limit.

3. **Count Frequency**: Count how many data points fall into each class. This is the absolute frequency.

4. **Calculate Relative Frequency**: The relative frequency of a class is the absolute frequency of that class divided by the total number of data points. It represents the proportion of the data that falls into that class.

5. **Draw the Histogram**: On a graph, plot the classes on the x-axis and the relative frequencies on the y-axis. Each class is represented by a bar; the height of the bar corresponds to its relative frequency.

6. **Estimate the Distribution**: Look at the shape of the histogram to estimate the distribution. If the bars gradually increase and then decrease, it might be a normal distribution. If they increase quickly and then decrease slowly, it might be a right-skewed distribution, and vice versa for a left-skewed distribution.

7. **Discuss the Skewness**: If the distribution is symmetrical, it has no skewness. If the distribution has a long tail to the right, it is right-skewed (or positively skewed). If it has a long tail to the left, it is left-skewed (or negatively skewed). The skewness can give you insights into the data. For example, a right-skewed distribution might indicate that there are a few unusually high values.

Remember, this is a general guide. The specific steps might vary depending on the nature of your data and the requirements of your task.
