Below mentioned are some of the important points to be remembered from Class 7 Maths Chapter 3, Data Handling.

**Data:**The data that is collected needs to be organised in a proper table so that it becomes easy to understand and interpret.**Average**: An average is a number that represents or shows the central tendency of a group of observations or data.**Central Tendencies:**Arithmetic mean is one of the representative values of data.

Mode is another form of central tendency or representative value. The mode of a set of observations is the observation that occurs most often.

The Median is also a form of representative value. It refers to the value which lies in the middle of the data, with half of the observations above it and the other half below it.**Bar Graph:**A bar graph is a representation of numbers using bars of uniform widths.

Double bar graphs help to compare two collections of data at a glance.

**Ans:** Mode is another form of central tendency or representative value. The mode of a set of observations is the observation that occurs most often. The Median is also a form of representative value. It refers to the value which lies in the middle of the data, with half of the observations above it and the other half below it.

**Ans:** When a coin is flipped, there are 2 outcomes, either Head or Tail. The probability of getting a head or a tail is equal ∴ to the probability of our team starting, P = 1/2.
