Spreadsheet Tool : OO Calc II

(i) Two ways in which the cells in the first row have been formatted are:

1. The cells B2, C2 and D2 are merged.
2. The text has been made bold and in uppercase.

(ii) The values shown in range B4:F15 have default alignment as the numbers are right aligned by default.

(iii) To display multi-line text in cells, we can select the cells and right click on the selection and select Format Cells option. From the Format cells window, select Alignment tab and select on 'Wrap Text automatically' property and click OK.

(iv) The command 'Wrap Text Automatically' has facilitated the setting of multi-line text.

(i) The two cell ranges that have been used to create this graph are [A4 : A13] and [F4 : F13].

(ii) Graphs offer a visual representation of data that simplifies complex information. They enhance understanding, aid in comparisons, highlight exceptions, and facilitate data storytelling, making them more effective than spreadsheets for conveying insights, engaging audiences, and guiding decision-making.

(iii) 'Lunchtime Sandwiches Sales' can be an appropriate title for above chart.

(iv) The data range of the Y-axis is [A4 : A13].

(v) The name of above chart type is column chart.

(vi) Another chart type that would be equivalently effective in conveying the information as above chart is bar chart.

(vii) If a pie chart were created with the same data ranges, it could easily compare the profits earned through different fillings of sandwiches.

(a) A suitable graph that Gina could use to display this information is a bar graph. Each student's spending on magazines can be represented by a separate bar, allowing for easy comparison between different individuals.

(b) Gina can use her computer to create a bar graph by entering student names and their spending data into a spreadsheet software like OpenOffice Calc.

Then, she can select the data, choose a bar chart type, customize labels, colors, and axes, save and insert the graph into her project.

(a)

(i) The content of cell A5 is text.

(ii) The format of cell B1 is a date.

(iii) The content of cell D5 is a formula.

(iv) The format of cell D5 is currency.

(b)

(i) The given graph is a pie graph.

(ii) The given graph is a bar/column graph.

Chart

Reason — Data represented in a worksheet can be easily understood by a chart.

Bar

Reason — Bar charts generated from a football statistics spreadsheet could compare the performance of the team from year to year.

Line

Reason — Line chart will show the direction of change in numbers over a period of time by connecting data points.

Line

Reason — Line chart can track and compare measurements such as temperature and show trends and comparisons.

Bar

Reason — Bar chart displays bars side by side.

Pie

Reason — Pie chart generated from spreadsheet data would compare values that represent parts of a whole.

Compare groups of data

Reason — Bar Charts are MOST effectively used to compare groups of data.

Line

Reason — A line chart is used to represent data points by connecting them with lines, making it easy to visualize trends and changes over time.

generally arranging data in worksheet

Reason — General arrangement of data is known as formatting.

Cells

Reason — To format text in a worksheet, Cells option will be selected from the Format menu.

Chart

Reason — Chart is a pictorial representation of worksheet data.

Row chart

Reason — Row chart is not a legal chart type in OOo Calc.

chart

Reason — A chart is a graphical representation of worksheet data.

Pie

Reason — In Pie chart, only one data series can be plotted.

Embedded

Reason — An embedded chart is inserted directly into a worksheet alongside the data it represents. This allows us to visualize and analyze the data in a graphical format within the same worksheet.

Stacked Column or Stacked Bar

Reason — A Stacked Column or Stacked Bar chart is used to represent data where each column (or bar) is divided into segments, and the height of each segment represents the proportion of a specific category within the whole. It's particularly effective for displaying data with multiple categories and comparing their contributions to the total.

XY

Reason — Scatter chart is also known as XY chart.

Line chart

Reason — A Line chart is a graph that is used for comparing changes in data over a period of time.

Handles

Reason — Small boxes around a part of a chart that indicate that it is selected are called Handles.

Embedded chart

Reason — An embedded chart is inserted directly into a worksheet alongside the data it represents. This allows us to visualize and analyze the data in a graphical format within the same worksheet.

Title

Reason — The Title tells the name of a chart.

Pie chart

Reason — In a pie chart, the entire data is shown as a circle (like a pie). The different parts of the data are shown as slices of the pie. The size of each slice shows how much it contributes to the whole data. This helps us see how different parts compare to each other and how they make up the whole.

Column chart

Reason — In a column chart, multiple data sets are compared by stacking their vertical columns on top of each other to visually show the total and the contribution of each component to the total.

Legend

Reason — A Legend is the key to a chart ; it tells what colour or pattern corresponds to a specific piece of data.

Bar chart

Reason — In a bar chart, each piece of data is represented as a horizontal bar, and the length of each bar indicates the value of that data point. When multiple data sets are compared side by side, the bars can be stacked next to each other to visually show the total and the contribution of each component to the total.

(i) True
Reason — Graphs are visual representations that allow viewers to quickly identify trends and patterns in data.

(ii) True
Reason — Graphs are visual representations, thus making it easier to grasp and understand information.

(iii) False
Reason — Graphs are designed to enhance data visualization and understanding. They generally make it easier, not harder, to identify the main point or trends in the data.

(iv) True
Reason — Graphs indeed introduce a visual model to a presentation, helping to illustrate data patterns and trends more effectively than raw numbers.

(v) False
Reason — Graphs are specifically designed to show changes and relationships in data, making them a powerful tool for data visualization.

(vi) True
Reason — Line graphs are particularly effective at displaying changes over time, as they connect data points with lines, highlighting trends and fluctuations.

(vii) False
Reason — Line graphs and histograms are different. Line graphs display the relationship between two variables over a continuous range, while histograms show the distribution of data within intervals or bins.

(viii) True
Reason — Pie charts are suitable for illustrating how different parts contribute to a whole, providing a clear visual representation of proportions.

(ix) False
Reason — Pie charts are best used to show the proportion of parts in relation to a whole.

(x) True
Reason — Both bar graphs and line graphs are excellent for presenting trends in data. Bar graphs use bars of varying lengths to compare different categories, while line graphs depict changes over time or other continuous variables using lines connecting data points.

Group together the selected cells and center the content.

Reason — The given button means to group together the selected cells and center the content.

Pie

Reason — The given chart is a pie chart as it shows the parts of a whole.

Yes

Reason — We can highlight the given cells by pressing Shift key and clicking on the cells — A14, C14, D8 and E7 while keeping the Shift key pressed. Once the given cells are highlignted, we can click on the Bold button on the Format toolbar to bold the contents of the cells.

No

Reason — In OpenOffice Calc, if we initially create a bar chart with a specific range of data and then add December figures to the end of that range, the chart will not automatically update to include these new figures. We will need to manually adjust the chart's data range to encompass the new data (including December figures) in order to accurately reflect them in the chart.

No

Reason — In OpenOffice Calc, if we choose "File > Print" from the menu, the grid lines might not be printed by default. Grid lines are typically not included in the default print settings. To print grid lines along with our data, we would need to enable the option to print grid lines before printing.

No

Reason — When we insert a column in a worksheet, we need to select either 'Insert Column Before' or 'Insert Column After' option. Depending on our selection, the new column is inserted either on the left or the right of the selected cell.

The general arrangement of data in a worksheet is known as formatting.

Formatting makes our worksheet presentable. It can emphasize certain data, and can create a hierarchy of relative importance among different elements of data. With formatting, we can make some data to be bolder, rotated or in different colour. So, basically formatting provides worksheet a neater and more legible outlook.

The different components of a chart are as follows:

1. X-axis — This is the horizontal axis known as category.
2. Y-axis — This is the vertical axis known as value axis.
3. Data series — This is the set of values we want to plot in the chart.
4. Chart area — This is the total region surrounding the chart.
5. Plot area — This is the area of chart in which our data is plotted. The plot area is bounded by axes in a 2-D chart.
6. Chart Title — This is the descriptive text aimed at helping user identify the chart.
7. Axes titles — These are the titles given to three axes i.e., X, Y and Z axes.
8. Legend — The legends help us identify various plotted data series. Each series can be uniquely identified by assigning a unique colour or pattern. This unique colour or pattern which identifies a data series, is known as legend.
9. Gridlines — These are the horizontal and vertical lines in the plot area. The gridlines are inserted in the chart to enhance its readability.
10. Data label — This is a label that provides additional information about a data marker, which represents a single data item or value coming from a worksheet cell.

(i) Embedded chart — A chart object placed inside a worksheet along with other data is known as an embedded chart.

(ii) Chart sheet — A chart sheet is a sheet having only a chart and no other data.
