Data Handling Checklist - Research Paper Example1.2Use entropy collection sheets to record data from a practical exercise (e.g. step temperature change all over time) (p264 Chapter 28). Solution There are a number of methods available to record the raw data.Let here we use tally chart to record the data related to measure the temperature change over time. The data recorded in flurry 1.2(a) is the raw data about the variation of temperature over time for a hot summer week. 1.3Identify strengths and weaknesses of different methods of data collection, e.g. tally chart - frequency hedge (p274 Chapter 28 submit Question 1).Answer.Strengths of come chart.A tally chart is a grid used to help clearly show breeding as it is collected.A good tally chart, -shows the information clearly. -have clear columns and headings.-uses lines to show numbers and a total number to show the frequency.Weakness of Tally chart -Tally chart is not a good preference to use for a large complex data collec tion. -Since Tally chart uses lines to show numbers, therefore for large data the Tally (lines) patterns are not however have an odd outlook but also cover a lot of space.Frequency TableWhen summarizing large masses of raw data it if practically useful to distribute the data in classes or categories and to determine the number of individuals belonging to each class called the class frequency. A tabular arrangement of data by classes together with the corresponding class frequency is called a frequency distribution or frequency table.The data organized in frequency table is termed as grouped data. Strengths of Frequency TableA frequency table can split data into classes or categories.By frequency table the actual number of scores as well as the % age of scores in each interval can be displayed. A frequency table can be used to summaries categorical, nominal, and ordinal data. It may also be used to summar
