Statistics
 

Statistics involves gathering, organising and analysis of data (normally numerical). In enables us to draw conclusions and make inferences on the basis of such analyses.

Descriptive statistics describe a set of data, while inferential statistics make inferences about large groups based on data from a smaller subset of the group. To infer means to draw a conclusion based on facts or premises. Thus an inference is the end result; a proposition based on the act of inferring.

Statistical data is critical to management of every commercial or government enterprise. Without statistics, our understanding of society, and the physical world; not to mention economics; would be greatly diminished.

  • Become familia with distributions, and the application of distributions in processing data.
  • Apply measures of central tendency in solving research questions
  • Demonstrate and explain the normal curve, percentiles and standard scores.
  • Explain methods of correlation that describes the relationship between two variables.
  • Make predictions with regression equations.
  • Determine how much error to expect when making the predictions.
  • Explain the basic concepts of underlying the use of statistics to make inferences.
  • Analyze the difference between the means of two groups with the t Test.
  • Describe the use of ANOVA (Analysis of Variance) in analysing the difference between two or more groups.
  • Apply the concept of Non Parametric Statistics

How will this course advance my career?

Learning Cloud programs have been developed in response to industry demand and are specifically designed to equip graduates with work-ready skills. Each participant will be trained and assessed in theory and in practical tasks and Real-world exercises are used throughout the program.

Studies prove, time and again, that college-educated workers earn more than those with only a high school qualification. College graduates often enjoy additional benefits, including greater job opportunities and promotions. Though the proof for greater earning potential exists, some might wonder whether the cost of the education warrants the overall expense in the long run.

College Graduate vs. Non-Graduate Earnings

The National Centre for Education Statistics (NCES) analyses employee earnings data biennially, according to education level. Findings indicate that workers with a qualification earn significantly more than those without. Since the mid-1980s, education has played a large part in potential wages, with bachelor's degree holders taking home an average of 66% more than those with only a high school diploma do. While college-educated workers' wages have increased over the past two decades, those with only a high school education have seen decreases in annual salaries in the same time period (nces.ed.gov).
