Important Points to Remember in Chapter -1 - Data and Charts from Asit Das Gupta Junior Maths 3 Solutions

1. Pictograph:

(i) A pictograph is the representation of data using images.

(ii) Pictographs represent the frequency of data while using symbols or images that are relevant to the data.

2. Steps to make Pictograph:

(i) Collect Data: First step is obviously collecting the data of the category you want to represent. Collect your data by appropriate means. Make a list or table of the data. 

(ii) Pick your symbol: Pick a symbol or picture that accurately represents your data.

(iii) Assign a Key: Sometimes the frequency of the data is too high. Then one symbol cannot represent one frequency. You must set a numerical value that one symbol will represent. This numerical value must be written along with the pictograph. Example one symbol of a smiley represents 3 students. This is the key to the pictograph.

(iv) Draw the pictograph: Final step is drawing your pictograph. Draw the two columns that represent the category and the data. Then draw the actual symbols that represent the frequencies. Remember that the symbols can be drawn as fractions as well if the frequency is not a whole number.

(v) Review your Data: And finally, review your pictograph and make sure it correctly represents the information that you wanted to relay. Don’t forget to check the labeling of your graph.

3. Tally Marks:

(i) The gathered information or data is represented in a tabular form using tally marks.

(ii) Tally marks are a quick way of keeping track of numbers in groups of five.

(iii) Tally marks are vertical lines '|'.
