STATISTICS
BREAKING DOWN
-
Statistical data is gathered using a sample procedure or other method. Two types of statistical methods are used in analyzing data: descriptive statistics and inferential statistics
Statistical analysis involves the process of gathering and evaluating data and then summarizing the data into a mathematical form.
Statistics is used in various disciplines such as psychology, business, physical and social sciences, humanities, government and manufacturing.
Descriptive statistics are used to synopsize data from a sample exercising the mean or standard deviation. Inferential statistics are used When data is viewed as a subclass of a specific population.
KURTOSIS
Data sets with high kurtosis have heavy talls, wich results in less investment risk
Data sets with low.kurtosis have light tails, which results in greater investment risk
Kurtosis measures whether the data are light-tailled or heavy-tailed that correlate to a standard distribution
-
MEAN
-
which shows the performance results of an investor´s portfolio invested in that same commodity over the same period.
The mean for a specified set of numbers can be computed in multiple Ways, including the arithmetic mean, which shows how well a specific Commodity performs over time, and the geometric mean
-
SKEWNESS
Most datasets, including commodity returns and stock prices, have either positive skew
Skewness describes the degree a set of data varies from the standard distribution in aset of statistical data
a curve skewed toward the left of the data average, or negative skew, a curve skewed toward the right of the data average
WHAT IS STATISTICS
Statistics studies methodologies to gather, review, analyze and draw conclusions from data
Some statistical measures include mean, regression analysis, skewmess, kurtosis, variance and analysis of variance.
Statistics is a form of mathematical analysis that uses quantified models, representations and synopses for a given set of experimental data or real-life studies
REGRESSION ANALYSIS
Regression analysis determines the extent to which specific factors such as interestrates, the price of a productor service, or particular industries or sectors influence the price fluctuations of an asset
