Clearing the concept of data handling

1. Pedagogy of Mathematics TOPIC-DATA HANDLING CLASS-6 SUBMITTED BY ISHA RASTOGI B. ED. II YEAR(07) BARCODE- PPT 1

2. Data handling Data handling is the process of collecting, organizing and presenting the data in such a way that is helpful to analyse and make the conclusion.

3. Types of data handling

4. P ictograph A pictograph is  a way to represent data using images . Each image in the pictograph represents a certain number of things. In other words, a pictograph uses pictures and symbols to convey information about the provided data.

6. Bar chart A bar chart or bar graph is  a chart or graph that presents categorical data with rectangular bars with heights or lengths proportional to the values that they represent . The bars can be plotted vertically or horizontally. A vertical bar chart is sometimes called a column chart.

7. Example

8. Line chart The line chart is  a simple, two-dimensional chart with an X and Y axis, each point representing a single value . The data points are joined by a line to depict a trend, usually over time.

9. Example

10. PIE CHART Pie Chart is  a circular representation of data . It is called a pie chart because the sectors of the circles are just like the slices of a pie. The area within each sector (slice) represents the size of the data. The area of each sector is directly proportional to the frequency of the data.

11. EXAMPLE

12. Histogram A histogram is  a graph used to represent the frequency distribution of a few data points of one variable . Histograms often classify data into various “bins” or “range groups” and count how many data points belong to each of those bins. A histogram has an appearance similar to a vertical bar chart, but there are no gaps between the bars. Generally, a histogram will have bars of equal width.
