3a. Outline  telling statistics

1- Inventio (invention)

  • Who  the subject of telling

  • What  the fact

  • When  the time location

  • Where  the field location

  • Why  the causes


3a. Outline  telling statistics

2- Dispositio (layout)

Deductive approach

Inductive approach

Time progression approach

Problems approach

Case / specific situation

Premise

Once upon a time…

Meaningful questions

Reflection

General Principles

Why something changed

Why in important to talk about…

Concepts

Developing arguments

Yesterday… Today…

Solutions (and concepts)

Consequences / other cases

Pratical consequences/examples

Tomorrow

Conclusions and consequences

Advantages-disadvantages approach

From point of view approach

Top-down approach

3a. Outline  telling statistics

3- Elocutio (expression)


3a. Outline  telling statistics

4- Actio (execution)

  • Stages:

  • Introduction

  • Development

  • Comments

  • Time/space use

  • Ending

  • Receivers’ feedback (Q&A)


3b. Tools  Depicting statistics

functions


3b. Tools  Depicting statistics

Perception of statistical Graph

Recognizing the code

Recognizing regularities

Carrying out comparisions and identify differences


3b. Tools  Depicting statistics

(i) Choosing a graph …

  • … by taking into account

  • number of involved variables

  • nature of data (level of measurement)

  • statistical information to be represented

  • … by preferring

  • a simple graph with reference to the audience

  • a clear graph instead of an attractive one

  • a correct graph with reference to data


3b. Tools  Depicting statistics

(ii) Preparing a graph


3c. Cloths  dressing statistics

  • Different aspects:

  • Text arrangement

  • Characters and fonts

  • Colours

  • Other aspect

    With reference to:

    • Balance

    • Harmony

    • Proportion

    • Elegance

    • Style

  • 1.2 the evaluating criteria

  • Suitability / consistency

  • Correctness

  • Clarity


1. Conceptual Framework

  • 1.3 the components of the transmission process

  • receiver / audience

  • available channel

  • available context / setting

  • Message’s Contents

4. The way forward


The way forward …

  • Emphasizing communicative aspects does not aim at exasperating the importance of communication with respect to the rest of statistical activities.

  • ICT societies increasingly require statistical information.

  • In order to attribute more value to statistics and to increase impact of statistics on reality, two processes need to be assessed:

  • data production and analysis

  • communication


The way forward …

The presented work summarizes the first stage of our study, aimed at defining the framework for quality assessment of communication in statistics.

The goal is to define the assessment technology by discussing with all the willing colleagues.
