- First Steps has developed a method for bringing STEM at work in construction to the notice of young people choosing their A-levels, and to their parents and teachers; it works like this.
Information panels that illustrate aspects of a subject (e.g. ground investigation, geotechnical design, construction, environment etc), and link directly to further information on education and careers in these areas, are inserted into the panels used for site hoardings.
Here is a link to one such panel https://ccsbestpractice.org.uk/entries/showcasing-careers-in-construction/?search_term=twickenham and here is the website that goes with this panel www.aspectsrevealed.co.uk/twickenham
Should you be in a position of advising a site owner or developer to include such a panel into their hoarding it may be helpful to know that Considerate Constructors, should they be using one of their Members, has adopted these information panels as their Best Practice.
- Those facing the prospect of having to use statistics in 2019 will find much needed support through the First Steps Stats Decision Tree more information on this is given at the end of this list.
- If you are faced with non-linear relationships such as decay functions and the like, and want to linearise them to ease analyses and comprehension, then you will find worked examples and simple instructions here.

Description of raw data
Raw data comes in many forms and it is crucial to understand what sort of data you have.
The Decision Tree helps you at every step; here is an example from one of its pages.
By way of background, data can be described as either discrete or continuous.
You may have data of a “Yes or No” type, where only one of two possibilities is recorded. For example: Was the SPT “N” value greater than or less than 25. Yes or No? This is an example of “discrete data”.
There is always a clear title for each activity – so
The description of raw data
Then background is provided
“Raw data is collected and comes in many different forms. Two types of data are described below, discrete and continuous.”
Then one or more examples are given – this one, for discrete data, is for clinicians.
The data can be of a yes – no type where only one of two possibilities for a number of patients is recorded, for example has the patient high blood sugar levels or not? Yes or No?
For ground engineers such an example could be “Does the value for cadmium exceed the the recommended threshold? Yes or No?
The decision tree explains every term in laymen’s language, so you don’t need to be a statistician to understand them. All the examples in the decision tree come from medicine because the tree was developed for medics – but the statistical methods they illustrate can be applied to any subject, not just medicine.
Three commonly used graphical tools used to describe statistical data are shown here. A bar chart, a pie chart and a box plot.
In the decision tree these and other graphical tools are described and the technical terms used in connection with them are explained.
But as you may have guessed, not every graphical tool can be used for any data set; here the decision tree helps you decide which graphical method is correct to use.
Data sets are described in quantitative terms, where each of the terms used is uniquely defined. More often than not both graphical and quantitative term types of description are required.
Tabular description tools
Tabular tools describe your data set in quantitative terms such as data tables and summaries, frequency, average and mode that are precisely defined.
This slide shows an extract from one page of the decision tree which defines, tables, summaries and frequencies.
Each of the terms mentioned under summaries on this slide like frequency, relative frequency, mode, mean and so forth is described and illustrated on this page of the decision tree.
Worked examples are also included to show you how to find the appropriate values for your data set by showing you how these values have been calculated step by step.
The next slide will take you to the home page of the website which contains the decision tree in its membership area.
About the decision tree
As mentioned before the Decision Tree was designed for medics but can be used for all subjects including geotechnics.
