Question

Fill in the blanks
1. A ------- is a collection of numbers gathered to give some meaningful information.
2. The data can be arranged in a tabular form using ---- marks.
3. A -------- represents data through pictures of objects.
4. In a bar graph, ------ can be drawn horizontally or vertically.
5. In a bar graph, bars of ------- width can be drawn horizontally or vertically with ------- spacing between them.
6. An observation occurring seven times in a data is represented as ---- using tally marks.

Answer 1

Hint: In this type of question we have to use the concept of data handling. We know that, Data handling means collecting the set of data and presenting it in a different form. Data is a collection of numerical figures that represents a particular kind of information. Data can be in any form. It may be words, numbers, measurements, descriptions or observations. Data can be represented in various forms through numbers, pictures, tables, graphics, etc. The most common type of graphical representation of data is through bar graphs. A bar graph represents a visual interpretation of data with the help of vertical or horizontal rectangular bars of equal width which are uniformly spaced with respect to each other, where the lengths of the bars are proportional to the data to be represented. To get particular information from the given data quickly, the data can be arranged in a tabular form using tally marks.

Complete step by step answer:
Now, we have to complete the given statements by filling the correct words in the blank space.
1. A data is a collection of numbers gathered to give some meaningful information.
2. The data can be arranged in a tabular form using tally marks.
3. A pictograph represents data through pictures of objects.
4. In a bar graph, lines can be drawn horizontally or vertically.
5. In a bar graph, bars of uniform width can be drawn horizontally or vertically with equal spacing between them.
6. An observation occurring seven times in a data is represented as \[\require\cancel\cancel{||||}||\] using tally marks.

Note: In this type of question students have to know detailed information about data handling. Students also have to remember the details related to representation of data in different forms. Also students have to take care about the representation of frequencies by using tally marks in tabular form of data representation.
