Pg 50 CBDA guide: 2.3.3 Explore data - • Data integrity: Can the data be trusted? For example, is the data
structurally correct?
• Data validity: Is the data truly representative of an underlying construct? For example, is Win ratio a good measure of monthly sales performance?
• Data reliability: If data is collected more than once, will the same results be obtained? For example, will a survey respondent answer a question differently on different days of the week?
• Data bias: Does the data portray an accurate picture of a given situation? It indicates underlying quality issues which may involve issues with integrity, validity or reliability. For example, are employees overestimating the quality of their work or do we have a situation where the survey participants are not a representative sample of the population?
