ICT Mathematics Project - Essay Example Averages The mean, median and mode are the measures to determine the central tendency of test data. As the data sets are not grouped the mean is achieved through summing all values (x) of the test data and dividing by the total number of values (n) i.e. 500. Similarly the median for ungrouped data is estimated by finding the middle value of the test data when arranged in ascending order. Mode for ungrouped data is found by spotting out the most occurring value of the data set. In this case, mode for house is 146, while that for car is 0. Table 1 Mean, Median and Mode of Raw Datasets House Car Mean 354.174 276481.878 Median 359 217174 Mode 146 0 Using mode we can know which value mostly contributes in the mean value estimated. Standard Deviation and Variation Mean, median and mode give limited information about the data. E.g. two data sets having the same mean may be broadly apart in their value from one another. So, the measures of Standard Deviation (s) and Variation (v) were used t o estimate how far each value of the dataset is from the mean of the dataset. The high standard deviation and variance values of the car data indicates the wide spread of data from the mean. The relatively smaller standard deviation and variance value of the house indicates that the data lies relatively close on either sides of the mean as compared to the car. As the data sets are ungrouped, the formula used for estimating standard deviation was: Squaring the value of standard deviation gives us the Variation. Table 2 Variance and Standard Deviation of Raw Datasets House (in 10,000rmb) Car Variance 39872.45172 69623323280 Standard Deviation 199.6808747 263862.3188 Standard Deviation and Variance is used to understand what a normal value is for a data set. For example, using the mean value of House from Table 1 (i.e. 354) and considering the above table, the value of 199 indicates that all data values that generate SD value as 199 are normal values. Any value outside this range is co nsidered as an outlier i.e. House value is either too low or too high. Range and IQR The mean, median, mode, standard deviation and variance are not able to indicate the spread of the data. So, Range and IQR are two measures of spread. Through range of house and car, we would know the difference of the lowest and highest values. In case we wish to know the median of the middle 50% of data, we would use the Interquartile Range. This specialized version of range would tell us the difference of the middle values of the first and third halves (25th and 75th percentile) of the data that is arranged in ascending order. Table 3 gives the range and IQR of the datasets. Table 3 Range and IQR of Raw Datasets    House Car Range 689 998897 Q1 180 72017.5 Q3 515 339674.75 IQR 335 267657.25 The value of Range of car tells us the difference of the lowest and highest value of the entire data set. IQR, on the other hand, provides us with the range of only the middle 50% subset of the dataset. Diff erence of the two measures from Standard Deviation is that as SD considers all data points, so the effect of any outlier data points is accounted for as well while estimating the mean which is undesirable. With range the spread estimated is intended to include the outlier data points. With IQR, as only the middle points of data portions are considered, the extreme or outlier data points are ignored, unlike the standard deviation. Scatter Plot of Raw

The government is proposing to introduce penalty duties of 30% on all Essay

The government is proposing to introduce penalty duties of 30% on all manufactured imports where the importer fails to prove that the producer is reducing its carbon emissions by at least 3% per year - Essay Example The plan will affect the lives of the general public in terms of costs of commodities in the local markets and loss of jobs. Economically, the amount of imported goods will decrease and trade balance might shift to the exports. There are scholars who have come up with better proposals that the government should go through and determine which one is most viable. The proposed plan has its pros and cons but the pros outweigh the setbacks. It is in everyone’s best interest to fight global warming at any cost. The government should look into providing compensations to the affected bracket of the citizens by the proposal. There should also be tax cuts introduced if the proposed plan takes effect. The government should also provide incentives to business firms to reduce emission of carbon. The British government has been working on reducing air pollution for decades. Environmentalists have made sure that the government keeps on its toes on the issue of emissions especially from manufacturing plants within the country. Emission of carbon and other gases that pollute the air and consequently contribute to the rise in global warming are being discouraged. To address this, the government has devised incentives that will ensure that local manufacturing industries adhere to the newly drafted emissions law. Companies are required to purchase permits from the required authorities according to their level of emissions. Global warming is a global issue hence the British government in conjunction with other countries worldwide has engaged in talks on the most feasible way to tackle emissions. It is during these talks that the participants devised a strategic plan that will ensure that every individual and company observes the requirements of emissions. The following report to The National business league will focus on the proposed plan to introduce penalty duties of 30% on all
