When you enter the **Statistics** app, you must type your data in a two-column table. You can add up to 3 data tables.

- In the first column (
**Values**), enter the values of your statistical data. - In the second column (
**Sizes**), enter the frequencies/sizes associated with each value in your dataset, i. e. the number of occurrences of each value.

When you fill in the first column, the second column is automatically filled in with the value $1$. This means that each of the values in your statistical data appears only once in the set. Change the sizes values in the second column if the values in your statistical set appear more than once.

Like, for example:

Let’s consider the following statistical data: $1$, $1$, $1$, $2$, $3$, $3$, $4$, $5$, $5$.

To enter this statistical data in the table, proceed as follows.

Values V1 | Sizes N1 |
---|---|

$1$ | $3$ |

$2$ | $1$ |

$3$ | $2$ |

$4$ | $1$ |

$5$ | $2$ |

You can also enter frequencies in the

Sizescolumn.

Once you have typed your data into the table in the **Data** tab, you can plot it as a histogram.

- Select the
**Histogram**tab at the top of the screen. - Confirm by pressing
**OK**.

You then see the histogram that displays your data.

Once you have typed your data into the table in the **Data** tab, you can plot it as a box plot.

- Select the
**Box**tab at the top of the screen. - Confirm by pressing
**OK**.

You then see the box plot that displays your data.

Once you have typed your data into the table in the **Data** tab, you can display the statistical variables: mean, standard deviation, median,…

- Select the
**Stats**tab at the top of the screen. - Confirm by pressing
**OK**.

You then see the table of statistical variables.

You can delete a row from the table by selecting a cell in that row and pressing **DEL**.

You can change the content of a cell by selecting it and typing a new value with the keyboard.

You can delete all the values in a column of the table.

- Select the name of the column you want to clear. Confirm by pressing
**OK**. - The column options menu opens. Select
**Clear column**and confirm with**OK**.

Clearing the **Values** column also clears the **Sizes** column.

Clearing the **Sizes** column fills this column with the value $1$.

You can create a column of the data table using a formula involving another column.

- Select the name of the column you want to fill. Confirm by pressing
**OK**. - The column options menu opens. Select
**Fill with formula**and confirm with**OK**. - Type your formula using the name of another column. For example, if you want column V2 to be filled with the values of V1 divided by 2, write
`V1/2`

in the text field at the bottom of the screen. Then press**OK**.

To enter a capital letter, press **shift** then **alpha** then the letter to display.

When you are in the **Histogram** tab, you can read the numbers and frequencies in the bar at the bottom of the screen for each rectangle. The intervals represented by the rectangles are also displayed.

To move the selection to another rectangle in the histogram, use the **Left arrow** and **Right arrow** keys.

To move to another data set, use the **Up arrow** and **Down arrow** keys.

You can change the width of the histogram rectangles (bin width) and the start value of the data set.

- Press
**OK**. - The histogram settings menu opens. Enter the values for the width of rectangles and the start of the set. Confirm by selecting the
**Validate**button and pressing the**OK**key.

In the **Box** tab, you can read the statistical variables below the box plot:

- Minimum
- First quartile
- Median
- Third quartile
- Maximum

To move the cursor, use the **Left arrow** and **Right arrow** keys.

To move to another data set, use the **Up arrow** and **Down arrow** keys.

The **Stats** tab displays the statistical variables calculated using the data in the **Data** tab:

- Total size
- Minimum
- Maximum
- Range
- Mean
- Standard deviation
- Variance
- First quartile
- Third quartile
- Median
- Interquartile range
- Sum
- Sum of squares
- Sample standard deviation
