Data Analysis The investigation I did was to find the resistance of a piece if wire. The piece of wire is my dependent variable throughout the investigation. I changed the length of the wire in order to measure the resistance of each length. Plan In this investigation‚ a simple circuit will be set up to read the voltage and current when the length of the wire changes. The length will range from 10cm-80cm with intervals of 10cm. The length of the wire will be changed by moving the crocodile clip

Data Preprocessing 3 Today’s real-world databases are highly susceptible to noisy‚ missing‚ and inconsistent data due to their typically huge size (often several gigabytes or more) and their likely origin from multiple‚ heterogenous sources. Low-quality data will lead to low-quality mining results. “How can the data be preprocessed in order to help improve the quality of the data and‚ consequently‚ of the mining results? How can the data be preprocessed so as to improve the efficiency and ease

discover the suitable ways of organizing experimental data in the form of tables and graphs by proficiently using Microsoft Excel. After being provided with a set of experimental data‚ a graph is then created. The graph contains useful information such as the slope‚ which could give the density value. The calculation of significant figures was one of the key objectives in this lab as well. Significant figures are essential to interpreting data because they allow for increased precision and accuracy
