At a glance
Last updated
D599 Data Preparation and Exploration (DTAN 5218, 3 CUs in the September 2026 WGU catalog) is the first course of the M.S. Data Analytics term 2: data science, data engineering, and decision process engineering tables alike. Per the catalog description it applies analytical programming skills to the early steps of the data analytics life cycle: cleaning data for structure, accuracy, and quality, interpreting descriptive and inferential statistics and visualizations, wrangling data for further analysis, and an introduction to hypothesis testing focused on parametric tests. The catalog names three prerequisites: D596, D597, and D598. Coursework Ninja completes D599 done-for-you, fixed quote in writing first. From $99. Independent of WGU.
Next question: what does D600 Statistical Data Mining build on top of D599?
Per WGU's published description, Data Preparation and Exploration applies analytical programming skills to the early steps of the data analytics life cycle. The course covers cleaning data to ensure the structure, accuracy, and quality of the data; interpretation of descriptive and inferential statistics as well as visualizations of data; and wrangling data to prepare it for further analysis. It introduces hypothesis testing, focusing on application for parametric tests, and it addresses communication skills and tools to explain an analyst's findings to others within an organization. The description names three prerequisites by title: The Data Analytics Journey, Data Management, and Analytics Programming.
Three concentrations carry it, all in term 2. The data science table (MSDADS 202408), the data engineering table (MSDADE 202408), and the decision process engineering table (MSDADPE 202408) each schedule it beside D600 Statistical Data Mining and D601 Data Storytelling for Varied Audiences, and it is the only course in that term gated by the entire term-1 trio. It is also the hinge of the whole degree: D600 Statistical Data Mining names D599 as its lone stated prerequisite, so a stall here cascades into the modeling course behind it. Message us the code in your portal and where you stand, and we quote a flat price in writing.

Coverage
What D599 completion covers
Cleaning for structure, accuracy, and quality
The description's first discipline: cleaning data to ensure its structure, accuracy, and quality. Graded work shows the cleaning decisions and their reasons, not just a tidy output file.
Descriptive and inferential statistics
Interpretation of both kinds of statistics is named, along with visualizations of data. The course grades the reading of the numbers, which is the step between running code and claiming a finding.
Wrangling for further analysis
Wrangling is named as preparation for further analysis, not as an end in itself. The deliverable is data shaped so the term's modeling and storytelling courses can actually run on it.
Parametric hypothesis testing
The description's statistics core: an introduction to hypothesis testing focused on application for parametric tests. Choosing the right parametric test for the question, and stating the result honestly, is where points live.
Explaining findings inside an organization
The closing row: communication skills and tools to explain an analyst's findings to others within an organization. The analysis is not finished until someone else can act on it.
Full degree plan integration
D599 alone is a single from $99. On a remaining master's list it folds into the flat $3,500 master's package with the written 6-month finish guarantee covering every course on the plan, this one included.

Bottlenecks
Where D599 stalls the MSDA's middle
D599 is the first course that grades statistics judgment on top of programming output, and it is the prerequisite wall in front of D600. These are the stalls we take over most often.
- Cleaning presented as before-and-after screenshots with none of the structure, accuracy, and quality reasoning the description names.
- Descriptive statistics reported while the inferential half of the prompt goes unanswered.
- A parametric test applied without checking whether the data fits the test, the application focus the description stresses.
- The findings explanation written for another analyst instead of for others within an organization, the audience the description names.
- The course deferred until late term, dragging D600 with it because the prerequisite chain allows no parallel run.

Questions, answered
Per the September 2026 WGU institutional catalog, Data Preparation and Exploration (DTAN 5218, 3 CUs) applies analytical programming skills to the early steps of the data analytics life cycle: cleaning data to ensure structure, accuracy, and quality; interpretation of descriptive and inferential statistics and visualizations; wrangling data for further analysis; an introduction to hypothesis testing focused on application for parametric tests; and communication skills and tools to explain findings within an organization. Prerequisites named: The Data Analytics Journey, Data Management, and Analytics Programming.
Per the current catalog, three master's tables, all in term 2: the M.S. Data Analytics data science concentration (MSDADS 202408), the data engineering concentration (MSDADE 202408), and the decision process engineering concentration (MSDADPE 202408). If your degree plan shows DTAN 5218, this is the course.
The catalog description names three by title: The Data Analytics Journey (D596), Data Management (D597), and Analytics Programming (D598), the entire term-1 trio of the degree. It is the only term-2 course gated by all three. Each prerequisite has its own completion page here, linked from this one.
WGU does not publish assessment formats in the catalog. The description centers applied cleaning, wrangling, and hypothesis testing, and we confirm the current format for your exact catalog year at intake. The fixed quote covers whichever assessment the course carries.
D599 is the lone prerequisite D600 names. The cleaning, wrangling, and statistics work here is the input the term-2 modeling course assumes, which is why the two run in the same term on all three tables but cannot truly run in parallel. Both pages are linked from this one.
One course starts at $99, with the exact figure fixed in writing once we know where you stand. On a longer remaining master's list, the master's package is $3,500 flat with the written 6-month finish guarantee covering every course on the plan, this one included.
