Chapter 9.2 : Average Rate (Lesson 1)

Rate is a ratio between two quantities with different units of measurement.

Rate allows us to express a quantity as a proportion of another quantity thus enable us to make comparison between different quantity.

Examples of rate being used in our daily life are:
1) Speed of a car, where the distance is measured against time (Kilometer per Hour or Meter per Second)

2) Buying of food and drink, where the price is measured against the weight or volume (Dollars per Kilograms or Dollars per Litres)

3) Frequency of Buses (Number of buses in operation per Hour)

4) Heart Rate (Number of beat per Minute)

The examples of rate in our daily life in countless.....

Thus give 2 examples of the use of Rate in your life and briefly describe how you can make use of these information to help you make better decisions in your life.

Please also refer to your Textbook 1B from Pg 9 to 11 and your Ace - Learning Portal for more materials and examples.

Hi 103s,

Welcome back after your second data collection session. 

I believe that each team will now have a set of data that is more precise and accurate as compared to Round 1.

We will aim to complete the following tasks today.

1) Consolidate and upload all data into the spreadsheet titled  "2010 Data Handling Traffic Survey School Level". This spreadsheet can be access through your Mathematics Google Site.


2) Let us now make use of an online sticky pad to search for more examples of Statistics Graphs in our daily life.
