A Statistical Audit Questionnaire for the Mathematical Sciences Introduction This questionnaire is design to enable you to obtain a profile of your knowledge, awareness and skills in statistics and data handling and may help you to formulate a personal development and training programme for these skills. You should complete each question by indicating the extent to which you are able to fully understand or do each of the topics. Your answers should be given using the ability scale shown in Table 1 below. Table 1: Definition of Ability Scale Ability Scale Description of ability 0 No ability – not competent. 1 Have some knowledge but no skill. 2 Can do with assistance on a day to day basis – have basic skill but need support to be effective. 3 Can do solo – proficient in the skill and able to show others how to use it. 4 Expert – can train others. A training example is given below, in Table 2, to illustrate how you should allocate a scale value for your answers. In the example the question is about ‘measuring of average’. Table 2: Measuring of Average Ability Scale Description of ability 0 No ability – not competent. 1 Can define the mean, median and mode. 2 Know how to calculate the mean, median and mode and the differences between them. 3 Know how to calculate the mean, median and mode; know which situations each should be used in and can explain this to others. 4 Know how to calculate and use the mean, median and mode to make comparisons between different samples or populations and able to explain this to others. 1 Mathematical Scientist Statistical Skills Audit Questionnaire Please answer all questions in all of the following sections. You should use Table 1 as your reference when indicating your level of ability. Section 1 Understanding the problem solving approach How would you rate your ability in each of the following? Description of skill topic When confronted with a problem: Ability scale No Some ability knowledge Basic skill Proficient Expert Planning an investigation and defining the problem Identifying relevant questions that need answering Recognising what data needs to be collected Choosing appropriate methods for collecting the data Collecting appropriate data Assessing the quality of the data Identifying appropriate ways of displaying the data Identifying appropriate numerical summaries of the data Discussing initial questions in the light of results obtained Recognising whether additional questions need to be answered Deciding on action to take in light of the results You can use this space to make some notes to remind yourself of your needs in these skills and to comment on how and why you have answered individual items. 2 Section 2 Recognition of population structure How would you rate your ability in each of the following? Description of skill topic Ability scale No Some ability knowledge Basic skill Proficient Expert Identification of a target population Deciding what needs to be measured Identifying measurement scales Deciding on appropriate sampling methods Discriminate between population and sample You can use this space to make some notes to remind yourself of your needs in these skills and to comment on how and why you have answered individual items. Section 3 Summary / description of samples How would you rate your ability in each of the following? Description of skill topic Ability scale No Some ability knowledge Basic skill Proficient Expert Using box-plots Using stem and leaf diagrams Using bar charts for discrete variables Using histograms for continuous variables Using scatter diagrams Using time series plots Tabulating sample data Measuring average (including mean, median and mode) Measuring spread (including range and standard deviation) Using mean and standard deviation to describe a distribution Distinguishing between discrete and continuous distributions Recognising patterns in time series data You can use this space to make some notes to remind yourself of your needs in these skills and to comment on how and why you have answered individual items. 3 Section 4 probability and uncertainty How would you rate your ability in each of the following? Description of skill topic Ability scale No Some ability knowledge Basic skill Proficient Expert Measuring uncertainty using probability Using tabulated data to calculate probabilities Calculating probabilities for conditional events Using probability to measure risk You can use this space to make some notes to remind yourself of your needs in these skills and to comment on how and why you have answered individual items. Section 5 randomness and sampling variability How would you rate your ability in each of the following? Description of skill topic Ability scale No Some ability knowledge Basic skill Proficient Expert Understand how common causes (inherent or natural variation) and special causes (external source of variation) can impact on a process Using graphs to illustrate variability Using summary measures to illustrate variability You can use this space to make some notes to remind yourself of your needs in these skills and to comment on how and why you have answered individual items. 4 Section 6 inferring population characteristics from samples How would you rate your ability in each of the following? Description of skill topic Ability scale No Some ability knowledge Basic skill Proficient Expert Estimating parameters of interest (e.g. mean and standard deviation) Calculating interval estimates of parameters Using basic statistical tests e.g. z, t and chisquared tests Measuring association using correlation Using simple linear regression Understand how bias can arise in measurement Understand how bias can arise in sampling Addressing problems of bias You can use this space to make some notes to remind yourself of your needs in these skills and to comment on how and why you have answered individual items. Section 7 Statistical methods How would you rate your ability in each of the following areas? Topic Ability scale No Some ability knowledge Basic skill Proficient Expert Sampling methods Experimental design Generalised linear models Bootstrapping Bayesian statistics You can use this space to make some notes to remind yourself of your needs in these skills and to comment on how and why you have answered individual items. 5 Section 8 Statistical Software Please indicate what statistical software you are familiar with and state your level of ability for each using the ability scale.
