## FAQs on RD Sharma Class 8 Solutions Chapter 24 - Graphical Representation of Data As Histograms (Ex 24.1) Exercise 24.1

**1. Explain the different shapes of the Histogram.**

There are five shapes of the Histogram which have been mentioned below:

**Bell-Shaped**: A single peak can be found in a bell-shaped Histogram.**Bimodal**: The term "bimodal Histogram" refers to a Histogram with two peaks.**Right Skewed**: A right-skewed Histogram is skewed to the right. The Bars of the Histogram are skewed to the right in this Histogram.**Left Skewed**: A Histogram that is skewed to the left is known as a skewed left Histogram. The Bars of the Histogram are skewed to the left in this Histogram.**Uniform**: A uniform Histogram is one in which all of the Bars are roughly the same height.

**2. What is the difference between a Bar chart from a Histogram?**

The main difference between Histograms and Bar Graphs is that Bars in a Bar Graph are not adjacent to each other. And the other is written down below.

**Bar Graph**: A Bar Graph is a Graphical representation of categorical Data made up of rectangular Bars whose length is proportional to the value represented.**Histogram**: A Histogram is a Graphical representation of Data in which the Data is divided into continuous number ranges, each of which is represented by a vertical Bar.

**3. Are there some tricks for making a Histogram?**

Listed below are some tricks to make a Histogram:

When drawing a Histogram, choose the scale on the vertical axis and look for the highest number that divides all the frequencies. If there isn't one, look for the highest number that divides the majority of the frequencies.

A Histogram is a Graph that shows how continuous Data is summarised.

The visual interpretation of continuous Data is provided by a Histogram.

The horizontal and vertical axes' scales do not have to begin at zero.

A Histogram's Bars should not have any gaps between them.

**4. What is the difference between skewed right and skewed left Histogram?**

A long left tail characterises a left-skewed Histogram. Negatively skewed Histograms are also known as left-skewed Histograms because of their long tail in the negative direction on the number line. Moreover, the mean is on the left of the peak.

The right tail of a right-skewed Histogram is long. Positive-skew Histograms are also known as right-skewed Histograms because of their long tail in the positive direction on the number line. In addition, the mean is to the right of the peak.

**5. How to draw a Histogram?**

Mark the Class intervals on the X-axis and the frequencies on the Y-axis to get started.

Both axes' scales must be the same.

Intervals between Classes must be exclusive.

Draw rectangles with the bases representing the Class range and the heights representing the frequencies associated with those intervals.

Because the Class limits are marked on the horizontal axis and the frequencies are indicated on the vertical axis, each Class interval is represented by a rectangle.

If the intervals are equal, the height of each rectangle is proportional to the corresponding Class frequency.
