2ANALYTICAL METHODS FOR ENGINEERINGTask 1A frequency distribution is a table summarizing the counts of incidence or frequency ofeach data point in a dataset. However, when the dataset consists of continuous data values, thedata is then represented a set of intervals.The frequency table then gives the frequency ofincidence in those ranges or intervals of data values derived from the dataset (Holcomb, 2016).A histogram is a graphical representation of the data. It is a bar chart which shows thecount of incidence of data points within sets of intervals which have been derived from thedataset.A cumulative frequency chart, as its name suggests plots the cumulative frequency ofeach interval.A median or second quartile is the data point under which 50% of the dataset lies. Thefirst and second quartile under which 25% and 75% of the dataset lies respectively. Thecumulative frequency chart could be used to graphically identify the median and the other twoquartiles. The x-value in the chart corresponding to value of the y-axis which corresponds withrespect to the cumulative frequency plot, to half or 50% of the total count is the median. The firstand third could be located in a similar manner by referring to the value at x-axis corresponding tothe 25% and 75% of the y-axis.The frequency table, histogram and cumulative frequency chart of the two sets of data areas follows:
