HI6007 Statistics and Research: Export Market Analysis Report T1 2019

This assignment focuses on the statistical analysis of export markets, specifically examining the top eight export markets for goods and services. It includes a comparison of data from 2004-05 and 2014-15, presented in both tabular and graphical forms. The analysis identifies shifts in market dominance, with China emerging as the leading export market in 2014-15. The assignment further explores grouped frequency distributions, relative frequency plots, cumulative frequency plots, histograms, and ogive curves related to umbrella sales data, providing insights into sales patterns and grade distributions. The report utilizes statistical inference and data visualization techniques to interpret trends and distributions, referencing established works in the field of statistics for management and economics.

c. The plot indicates that that in the period 2004-05, Japan was the leading export
market for goods and serviced (Keller, 2015). However, in the period 2014-15 China
was the leading export in the top eight export markets. In general, the plot suggests
that there was an increase in the quantity of export between the periods 2004-05 and
2014-15. New Zealand and the United Kingdom did not show a significant change in
their export value. The value of export from the United Kingdom slightly decreased
from A$ 9.2 billion to A$ 8.6 billion. This was th4 only country among the top eight
export market that had a decline in their export value.

The plot indicates that there was a general decline in the proportion of market share
among the top eight exports markets for goods and services. China had a tremendous
increase in its market share from 15.4% to about 40.4%. New Zealand and the United
Kingdom had the highest drop in market share from 11.8% to 5.5% and 8.9% to 3.8%
respectively. Thus, it can be concluded that although the market value of most of the
country increased, the market shared among the top eight export decreased (except for
China) (Silvey, 2017).

cummulative frequency
The plot indicates that the most frequent sale was 68. Most of the sales were made once and
thus they had a single entry (Chatfield, 2018).
