ICDL Data Analytics (ICDL) study plan

ICDL Data Analytics · Give each week a clear focus.

8 weeks · About 6 hours per week

Week 1

Data Analytics Fundamentals

  • Define the core stages of the data analytics lifecycle and order them correctly

  • Distinguish descriptive, diagnostic, predictive, and prescriptive analytics with a self-written example of each

  • Classify data types (nominal, ordinal, interval, ratio) and identify which summary statistics apply to each

  • Explain the difference between a population and a sample and when each is used

Your checkpoint

A one-page reference sheet covering the analytics lifecycle, the four analytics types with examples, and data-type rules, scored against a 10-question self-quiz at 80% or higher

Week 2

Data Analytics Fundamentals

  • Compute mean, median, mode, range, variance, and standard deviation by hand for a small dataset

  • Interpret what each measure of central tendency and spread reveals about a distribution

  • Identify outliers using the interquartile range rule and justify whether to keep or exclude them

  • Explain how sampling bias and confounding variables distort conclusions

Your checkpoint

A worked statistics worksheet showing hand calculations for two datasets plus a short written justification of outlier handling for each

Week 3

Data Analytics Fundamentals & Data Analysis and Visualization

  • Match each chart type (bar, line, scatter, histogram, pie) to the question it answers best

  • Select the correct visualization for a given dataset and analytical purpose

  • Identify misleading chart practices such as truncated axes and inconsistent scales

  • Sketch a draft chart for a small dataset and annotate why the chosen type fits

Your checkpoint

A chart-selection decision table mapping at least six analytical questions to appropriate chart types, with one annotated hand-drawn example

Week 4

Data Analysis and Visualization

  • Build a pivot table that summarizes a dataset by two dimensions with calculated fields

  • Apply sorting, filtering, and conditional formatting to surface top and bottom performers

  • Construct a scatter plot and describe the direction and strength of the relationship

  • Summarize key findings from a chart in two to three plain-language sentences

Your checkpoint

A single workbook or dashboard containing one pivot summary, one scatter plot, and a written three-sentence interpretation, reviewed against a self-made 8-point checklist

Week 5

Data Analysis and Visualization & Data Management and Reporting

  • Clean a messy dataset by removing duplicates, standardizing formats, and handling missing values

  • Document each cleaning decision and its rationale in a change log

  • Apply validation rules that prevent invalid entries in a data table

  • Compare a before-and-after summary to quantify the effect of cleaning

Your checkpoint

A cleaned dataset accompanied by a change log listing every transformation and a one-paragraph before-and-after comparison

Week 6

Data Management and Reporting

  • Design a relational table structure with a primary key and at least one linked table

  • Write queries or filters that extract a defined subset of records for a stated business question

  • Create a summary report that aggregates data by category and time period

  • Apply consistent naming, formatting, and labeling conventions across a report

Your checkpoint

A two-table relational dataset with three saved queries and one formatted summary report answering a specific question

Week 7

Data-Driven Decision Making

  • Translate a business problem into a testable analytical question with defined success metrics

  • Interpret a dataset's results and state a recommendation supported by the evidence

  • Identify at least two limitations or risks in an analysis and describe their impact on the conclusion

  • Present findings in a short narrative structured as situation, evidence, recommendation

Your checkpoint

A two-page decision brief containing the question, key metrics, one supporting chart, a recommendation, and a limitations section

Week 8

Data Analytics Fundamentals & Data Analysis and Visualization & Data Management and Reporting & Data-Driven Decision Making

  • Assemble a full end-to-end analysis from raw data through cleaning, visualization, reporting, and recommendation

  • Audit the deliverable against all four domain checklists and close any gaps

  • Complete a timed 40-question practice set covering all domains and review every missed item

  • Explain each missed concept aloud in your own words to confirm understanding

Your checkpoint

A complete capstone analysis package (cleaned data, chart, report, and decision brief) plus a practice-set score of 80% or higher with a written review of every error

Milestones

Week 2: Score 80% or higher on a self-made 10-question fundamentals quiz covering lifecycle, data types, and descriptive statistics

Week 4: Produce a chart-and-pivot deliverable that passes your 8-point checklist with no more than one failed item

Week 6: Demonstrate a cleaned, documented dataset and a formatted summary report generated from saved queries

Week 8: Submit the full capstone package and score 80% or higher on the timed mixed-domain practice set
