Analysing Data

By Hannah St Ledger

Trends

When looking at data, particularly graphs, a trend in the general direction in which something is going over time or across categories

• Think of a trend like a big-picture movement

  • Is something increasing, decreasing, or staying the same

Open Ended

Using this graph, identify at least 1 Trend

Examples of Trends

• Male sheep have a consistently higher lean meat yield than female sheep across all body regions

• The hindquarters has the highest lean mean yield for both males and females

Patterns

A pattern is something that repeats or follows a predictable arrangement

• Patterns help you spot regular behaviour in data
  

Open Ended

Using the graph, identify at least 1 Pattern

Examples of Patterns

• In each part of the body male sheep produce more LMY

• Hindquarter has the highest LMY for both males and females

• Saddle has the lowest LMY

Relationships

A relationship is when two or more variables are connected

• When one thing changes, what happens to the other?
  
  

Open Ended

Using the graph, identify at least 1 Relationship

Examples of Relationships

The relationship between sex (male or female) and LMY.

Male carcasses always have slightly higher LMY

​Identify 1 Trend, Pattern, and Relationship

Multiple Choice

What type of trend does this graph have?

• Upward trend

• Downward trend

Multiple Choice

What is the relationship in this graph?

• The amount of days and the weight gain of chickens

• The difference in weight of Layer and broiler chickens

• Weight gained

• All of the above

​Exit Ticket - Refining a RQ

Does gender have an effect on weight gain in lambs?

What does gender mean here?
How will weight gain be measured?
Are there any other variables that could be considered?
