Key Findings

  • 01A moderate, significant positive correlation exists between numerical skills and deal competency.
  • 02Numerical skills are positively related to being male and mathematical achievement.
  • 03Deal competency is positively related to age, mathematical achievement, and educational achievement.
  • 04Deal competency is negatively related to the amount spent on promotional food items in top-up grocery shops.
02

Application

Design takeaway

Designers and marketers should simplify the presentation of price promotions to ensure they are easily understood by a broad range of consumers, regardless of their numerical proficiency.

How to apply

When designing promotional offers, use straightforward comparisons (e.g., 'Save $X', 'Buy One Get One Free') rather than percentage discounts that require calculation, especially for mass-market products.

Project actions

  • 01Consider how different user groups might interpret promotional information differently.
  • 02When designing user interfaces for shopping, think about how numerical information is presented.
03

Method & Evidence

AimTo investigate how consumers' numerical skills and demographic characteristics influence their ability to determine the best deal during grocery shopping.
MethodQuantitative survey and statistical analysis
ProcedureA survey was administered online to collect data on participants' demographics, grocery shopping habits, subjective numeracy skills, and their ability to assess deals (deal competency). Statistical analyses, including multiple regression and Pearson's correlations, were performed.
Sample308 participants
ContextRetail grocery shopping and consumer behaviour

Variables

IV["Numerical skills (subjective numeracy scale score)","Demographic characteristics (gender, age, education, mathematical achievement)"]
DV["Deal competency"]
CV["Grocery shopping behaviours","Amount spent on promotional items"]
04

Strengths & Limitations

Strengths

  • +Introduces a novel scale for measuring deal competency.
  • +Investigates a practical aspect of consumer behaviour relevant to marketing.

Limitations

The subjective nature of self-reported numeracy can be a limitation, as individuals may overestimate their skills. The context of a grocery shop might not represent all purchasing decisions.

Reliability & validity

The use of established scales for numeracy and statistical analysis methods contributes to reliability. The novelty of the deal competency scale may require further validation for broader applicability.

Think critically

To what extent should designers tailor promotional content to different levels of consumer numeracy, and what are the ethical implications of such segmentation?

05

Design Principles

"Clarity in Value Communication: Ensure that the perceived value of a product or promotion is immediately understandable, minimizing reliance on complex calculations."

Understanding the relationship between numerical literacy and consumer decision-making is crucial for marketers and product developers. It informs how promotional strategies are designed and communicated, ensuring they are effective and understood by the target audience.

06

What This Means for Your Design

This research shows that if you're good with numbers, you're better at figuring out which grocery deals are actually the best. This is important because companies need to make sure their deals are easy for everyone to understand.

How to use in your project
