Revision on collection, tabulation and presentation of data
Statistics can be considered as a way or method used in the collection and organisation of data in order to interprets, predict and get other information required out of the data.
This data could be information about some people e.g. ages, weights, heights, examination scores, etc.
Collection of Data
Let us remind ourselves that there are two kinds of data namely:
(a) discrete data (b) continuous data
Discrete data are those which are obtained by direct counting e.g numbers of persons born on a particular days of the week, month of the year, etc.
Continuous data are those which require measurement before counting e.g number of persons of some age, height, weight etc.
Class Activity:
Collect and tabulate data on the days of the Week each member of the class was born.
Tabulation and Presentation of data
