This key or numerical value must be written along with the pictograph. This can be done by setting a numerical value that one symbol will represent. Assign a Key: Based on the frequency of the data, decide the frequency for one symbol.For drawing a pictograph to represent the number of hours spent on a particular activity, we can use an hourglass as a symbol. Review the data and Pick a symbol: Review the collected data and based on it pick a symbol or picture that accurately represents the data.In the above example, the data is already provided in the form of a table. Collect Data: Firstly, we need to collect the data of the different categories we want to represent.The below-given steps can be followed to represent the data given in the table in the form of a pictograph. The following table gives this data: Activity
We will represent the average hours spent by students on different activities. If we denote the number of times by 'N', and the value of each symbol by 'S', we get: Value of a category = Product of the number of times the symbol is used and the value of each symbol. Thus, after going through the above pictograph example, we come to the basic formula which is used to find the value of the data of the categories given in the chart/table. A fraction of an icon can also be used to show data.All the symbols/icons must be of the same size.In the above example, the key was 1 icon of the pizza representing 4 children. We use a key to denote the value of the symbol. Multiply the number of symbols for the given flavor with the value of each symbol.įor example, the number of children who liked Pepperoni = 2 \(\frac\) × 4 = 2 × 4 + (1/4) × 4 = 8 + 1 = 9 Key to a Pictograph We need to do simple math to understand how many children voted for each of the flavors.

Here, the symbol for a full pizza is used to represent data (i.e. The results were as follows:Ĭan you identify the most loved flavor by observing the above table? If 1 full pizza represents 4 children, then what would a quarter slice represent? The scenario that we discussed above represents information in a pictographic manner. Pictograph ExampleĪ survey was conducted for 40 children by a fast food junction to understand the demand for different flavors of pizza available in their outlet. Now after knowing the pictograph definition, let us understand pictographs using a scenario. They help in laying the foundation for data interpretation based on pictorial information. "A pictograph is a representation of data using images or symbols." Pictographs in maths are typically used in concepts like data handling. Pictographs are one of the simplest ways of representing data. We can represent the frequency of data while using symbols or images that are relevant using a pictograph.

The pictorial chart example "Barrie population" was created using the ConceptDraw PRO diagramming and vector drawing software extended with the Picture Graphs solution from the Graphs and Charts area of ConceptDraw Solution Park.In mathematics, a pictograph, also known as a pictogram, is the pictorial representation of data using images, icons, or symbols. The Barrie census metropolitan area (CMA) had a population of 187,013 residents, making it the 21st largest CMA in Canada." The city's 2011 population was subsequently revised to 136,063. In 2011 census, the city's population was originally reported as 135,711, making it the 34th largest in Canada. Barrie is within the northern part of the Greater Golden Horseshoe, a densely populated and industrialized region of Ontario. Although located in Simcoe County, the city is politically independent. "Barrie is a city in Central Ontario, Canada, on the western shore of Lake Simcoe. It was designed on the base of the Wikimedia Commons file: Barrie Population.jpg. This picture bar graph sample shows the Barrie population growth from 1981 to 2006.
