Task 2 – Using dataset and description below, answer the questions that follow:

You will upload onto Power BI (Desktop and/or Service), a dataset named ‘Census-Income (KDD) Data Set’ created by “Terran Lane and Ronny Kohavi, Data Mining and Visualization, Silicon Graphics. terran ‘@’, ronnyk ‘@’” available at

IMPORTANT NOTE: UCI website has useful information about the Census-Income (KDD) Data Set’, therefore it is very important to study the metadata before uploading the dataset into Microsoft BI.

Data Set Characteristics:   Multivariate Number of Instances: 299285 Area: Social
Attribute Characteristics: Categorical, Integer Number of Attributes: 40 Date Donated 2000-03-07
Associated Tasks: Classification Missing Values? Yes Number of Web Hits: 209458

Table 1: Census Income Data Set                                                             [Source: ISCTE-IUL, 2016]

This data set contains weighted census data extracted from the 1994 and 1995 Current Population Surveys conducted by the U.S. Census Bureau. The data contains 41 demographic and employment related variables.

The instance weight indicates the number of people in the population that each record represents due to stratified sampling. To do real analysis and derive conclusions, this field must be used. This attribute should *not* be used in the classifiers. One instance per line with comma delimited fields. There are 199523 instances in the data file and 99762 in the test file.

Given the description of the dataset, as shown in table 1,  you have been tasked with preparing data and curry out an assessment analysis report or dashboard on PowerBI.

Using a minimum of 1,000 words and excluding list of references, explain your work, interpret the results and reflect on your experiences:

  1. Explain how you built your Power BI report service (Microsoft, 2019) and the issues you faced. In particular, how you achieved the following:
    1. Given that table 1, shows that “Missing Data is Yes” what would you recommend for checking the quality of the data [4]
    2. Explain how to upload/retrieve dataset onto Power BI service [6],
    3. built your report/dashboard [8], and
    4. shared your report/dashboard with tutor and lecturer [2]
  2. Interpret the results of running your report/dashboard, using any four (4) suitable graphs that are interlinked, [12] (support your interpretation with visual evidence).
  3. Reflect on lessons learned, citing any noticeable trends from your findings [8] (support your answer with visual insights).
