Analyse Data using scenarios and goal seek with Libre Office Calc

Data analysis is one of the important aspects of routine work for any organization. The spreadsheet software is the best software for analyzing data.

Libre Office Calc is a spreadsheet software that is used to analyze data easily and effectively. Spreadsheet allows to represent the data in tabular form to do the following:

  1. retrieve
  2. correlate
  3. explore and visualize data to identify patterns, trends, and relationships
  4. manipulate data
  5. interpret results

Analysing data is the process to extract useful information for making effective decisions.

So let us begin Analyse Data using scenarios and goal seek with Libre Office Calc with Consolidating data.

Consolidating Data

Data consolidation is a tool that allows to use of a function and combine data from multiple sheets together and summarize data in a single worksheet.

In other words, Data consolidation refers to extracting data from multiple sheets and making a summary in a different sheet using a function.

To consolidate data, the following things are necessary:

  1. Prepare multiple sheets with common data entries
  2. Data types provided in the different sheets must match with each other
  3. All sheet labels should match
  4. The first column must be a primary column for data consolidation

Steps to Consolidate Data

To consolidate data follow the given steps:

[1] Prepare worksheets as follows and rename them as PT 1, and PT 2 respectively:

    • Product
    • Count(numbers only)
    • StDev(sample)
    • StDevP(population)
    • Var(sample)
    • VarP(population)
  2. Consolidation Ranges: Here the range of cells will be added. Ranges can be created or selected randomly.
  3. Source Data Ranges: This option contains name ranges defined through the Data –> Define Ranges option. By default -undefined- ranges are given.
  4. Copy Results to: This option specifies the range of cells where the result needs to be displayed.
  5. Add: To add range of cells for data consolidation.
  6. Delete: To delete range of cells from data consolidation.

Creating Subtotals

Libre Office Calc provides an option to Group records according to a specific column and creates an outline from them.

Subtotals in spreadsheets create an automatic group based on a columns having repeated data and aggregates the result in a group.

It uses a summary function like sum, max, min, average, etc. to group data in a spreadsheet. The data can be grouped into multiple columns. It can group subtotals on specific columns and sort them in ascending order or descending order.

Subtotals Dialog box in Libre Office Calc

To open the subtotal dialog box in the libre office calc follow these steps:

Click on the Data –> Subtotals option.

The subtotals dialog box in Libre Office Calc has the following options:

  1. Grouping and Options tabs: The subtotals dialog box contains tabs for groping records like 1st Group, 2nd Group, 3rd Group, and Options tabs. The grouping tabs (1st Group, 2nd Group, 3rd Group) provide options such as Group by to select a column for the subtotal group. It also allows selecting all columns for grouping.
    • Options tab: This tab has two options as follows:
      • Groups: The groups option has three sub options:
        • Page break between groups: Allows page break between groups
        • Case sensitive: Checks for case sensitivity for grouping column names
        • Pre-Sort area according to groups: Allows sorting and enables sort option
      • Sort: By selecting this option data can be sorted in Ascending or Descending order including formats and custom sort orders such as months and days.
  2. Calculate subtotal for: This option allows to select a column to compute the subtotal on it. All columns present in the worksheet are available here for selection. Any number of columns can be selected at a time for subtotal calculation.
  3. Use Function: It provides various functions to compute subtotal. These functions are : Sum, Count, Max, Min, Product, Count (Numbers Only), StDev(Sample), StDevP(Population), Var(Sample), VarP(Population).

Practical Activity – Creating Subtotals

Observe the data given below and create subtotals for the same.

What-if Scenarios

A what-if scenario is one of the spreadsheet tools that allows you to save a set of values under various names and present them under a specific name assigned. Users can create several scenarios on one spreadsheet.

What-if scenarios are used for the following purposes:

  1. To explore and compare values based on changing conditions
  2. It can provide optimization of output for any project
  3. It generates various outputs with different kind of input that allows users to choose the best result for them

Example Creating a Scenario

Let’s create a scenario for a team’s net run rate in a cricket tournament. Net run rate is calculated by the below-given inputs match by match:

  1. Runs scored in each match
  2. Overs faced in each match
  3. Runs given in each match
  4. Overs bowled in each match

The formula to calculate the net run rate is:


For each match, I have created a different scenario and named them as Match 1, Match 2 , Match 3 etc.

The screenshots are as follows:
