Hello students, in this session we are going to discuss the collecting data, organize it and graphing data. Let’s take a look step by step. To organize and graph data, firstly it should be properly collected. And there are various methods to collect the data according to our requirements.
Data collections mean store the data at a particular place and also describing that how it was collected. And in data collection we get the information from many source such as from persons. By the data collections we store the information at a particular place so that we can use this information for further use. Before data collection you should know about the types of data. Data may be primary and secondary, after finding the types of data we apply the collection methods, and they are also two types grouped and Un grouped.
Methods for primary data collection are: - Data collection through investigation, Data collection through telephones and Personal investigation methods.
Methods for secondary data collection are: - Official methods include the data collection from the ministry of finance and industry by using some tools. (know more about icse board , here)
Semi official methods include the data collection from the banks, board of railway.
After collecting data we need to organize the data. To organize the data generally we use tables. Because the retrieval and insertion of data and information in table is easy than any other.
Let talk about the graph of data, to do this we use several types of graphing methods such as : - pie chart, line plot, box plot, pictograph, map chart, bar graph, line graph, stem and leaf plot, frequency polygon and histogram that are mainly used.
I hope this information that i gave above will be truly useful for the Grade VI students.
In the next session we will discuss about Measures of central tendency/dispersion.
