Descriptive Statistic paper - Essay ExampleFrom the preceding(prenominal) data collected the column A represents high ATM purpose while B represents account bank note usage, the first data n high ATM usage has a mean tax of 10.3 and the minimum amount is 2 and maximum amount of 20, the standard deviation is 18.45 and for this reason the data is negatively skewedThe above chart shows negative skew for the high ATM usage, this states that to a greater extent of the data observations dwell on the lower measures of the data less data on the other hand lies on the high measure of the data.The data on debit card usage is also negatively skewed and this representation that more of the data observations lies on the lower measures of the data, less data on the other hand lies on the higher measure of the data.The mean of high ATM usage is 10.3 showing that there are more individuals using ATM, the mean of debit card usage is 0.43 showing that less people enforce debit cards. The mean is a measure of central tendencies of the data and they give us the probability of expected turnout. so from this measure it is clear that more people use ATM but less people use Debit cards.The standard deviation is a measure of dispersion from the mean, the higher the standard deviation whence the higher is the dispersion from the mean, however the lower the standard deviation then the lower is the standard deviation. In our encase the ATM usage standard deviation is 18.45 and this is higher than the deviation of debit card usage which is 0.25.The population standard deviation is a measure of dispersion from the mean for the entire population, In this case the ATM usage population standard deviation is 18.14 and the population standard deviation for debit card usage is 0.25, the population standard deviation helps us to determine the validity of data analysis of the try because a sample should be a representative of the entire population, therefore our sample is not nonrever sible and therefore represents the entire population due to the low errors on central
