Space and Colours, or Applied Psychology




TASK 1
Read the text on  Colours in the classroom.
Compare its graphics with this article.
Focus on fonts, colours, layout. 
Which of the texts is easier to read+comprehend? Which is easier to navigate? Which offers more consistent information?

TASK 2
Look at several professionally designed, information oriented web sites - e.g. 

Observe how they use colours and layout.
List your suggestions of do's and don't's into the comment to this blog entry.

Summary of required skills:

you should be able to

  • recognise and respect (use) the effect of various colours (shades, space, intensity) on human brain
  • apply columns/table formatting in html or doc to use the space wisely
  • effectively combine texts and relevant illustrations
TASK 3
  1. Open nvu or any web editor you prefer. 
  2. Focus on your moodle topic. Collect at least 8 items of different type (you can use those you already have)  - text paragraphs, headlines, images, links, graphics (arrows etc.).
  3. Organise these items into a html file, getting as much info as possible into a single screen: the user/reader should be able to access as much material as possible without the need to roll down.

Tips:
Insert a table to keep full control about the layout. 
Each row/column/cell parametres can be edited separately (right-click on the borderline to get the menu).
Use different font sizes and colours wisely.

Statistics

 


Summary - What should we know?

1. The meaning and method of Average, Mode, Median
2. The meaning and method of counting the Weighted Average
3. The meaning and formula for Correlation
4. The ways of recording and analysing the raw data
5. Choosing a suitable graphical representation of the survey results



Analysing research data

Task 1 

1. Download an example spreadsheet from capsa - go to folder PCSkills, file PcSkillsZakladyStatistiky.xls

2. Use the sum, average, mode and median formulas to get the first results. THINK about the type of data you are using and consider you want to learn - use the predefined questions and hypotheses.

3. In some surveys it is very important to mutually relate various findings -  to prove or disprove a correlation between two facts/answers. Identify the possibilities and explore the correlation within the data.

4. Prepare a graphical presentation showing the results. Decide which types of graphs are the most suitable.

Task 2 - Supporting activities

1. Downolad the excel file KorelacePriklad.xls form capsa. Use the formula explained in this link: Korelace v excelu - příklad to find out the correlations among the given sets of data.

2. Downolad the excel file Verejny... .xls form capsa and explore the formula used for counting individual teaching loads: =DSUMA(I7:J116;"Úvazek";L1:L2). How does it work, what does it summarise?

3. Study the articles linked below. You should understand, and be able to explain and apply at least the descriptive statistics. Ask the tutor for help if necessary.


Tips:
Pie graphs are used only when describing the split of a limited sum of recipients or other data.
Example: Identifying the use of potatoes in the kitchen:  50% get boiled, 25% are mashed, the rest is used to make soups.

Focus on the examples - try to understand the information in the data before dealing with the methods.
Consider real-life examples,  or use the real data to experiment with descriptive statistics.
