Excel Given here is a set of Y-X data points, using spread sheets least square fit the given data for a straight line Y = mX + c case. Mass (Y) 341.59 338.92 340.39 338.43 337.57 W (X) 0.01 0.02 0.03 0.04 0.05 The expressions for ‘m’ and ‘c’ are as follows. m = (n∑X*Y - ∑X * ∑Y)/[n∑X2 – ((∑X)2 )] c = (∑X2 ∑Y - ∑X * ∑X*Y)/[n∑X2 – ((∑X)2 )] From the least square fitting of the data calculate the parameters ‘m’ and ‘c’ hence the equation Y = mX + c Make a plot of original ‘X’ & ‘Y’ data showing the deviation of points from straight line. Fit the ‘TRENDLINE’ equation & compare the coefficients ‘m’ & ‘c’ with those obtained above.

bsnaksnjskxjxjxbbxhsjjabahajsjbsbyhhyhBHabahaA histogram is used to display the distribution of information or data over a continuous time period. ... Histograms may have a similar appearance to bar charts but unlike them, are used to plot the frequency of variable occurrences in continuous data. The frequency polygon is a curve that is drawn on the x-axis and the y-axis. The x-axis represents the values in the dataset while the y-axis shows the number of occurrences of each distinct category.
The frequency polygon can serve as an alternative to a histogram. Both visual representations perfectly reflect the shape of a distribution. However, unlike the histogram, the frequency polygon can be easily utilized to compare multiple distributions on the same graph. In some cases, a histogram and a frequency polygon can be used simultaneously to get a more accurate picture of the distribution shape.A frequency polygon is a visual representation of a distribution. The visualization tool is used to understand the shape of a distribution. Essentially, the frequency polygon indicates the number of occurrences for each distinct class in the dataset. In addition, the graph may be used to show the cumulative frequency distribution.Water pollution (or aquatic pollution) is the contamination of water bodies, usually as a result of human activities, in such a manner that negatively affects its legitimate uses.[1]: 6 Water pollution reduces the ability of the body of water to provide the ecosystem services that it would otherwise provide. Water bodies include for example lakes, rivers, oceans, aquifers, reservoirs and groundwater. Water pollution results when contaminants are introduced into these water bodies. For example, releasing inadequately treated wastewater into natural waters can lead to degradation of these aquatic ecosystems. All plants and organisms living in or being exposed to polluted water bodies can be impacted. The effects can damage individual species and impact the natural biological communities they are part of. Water pollution can also lead to water-borne diseases for people using polluted water for drinking, bathing, washing or irrigation.A frequency polygon is a visual representation of a distribution.
