| Výchozím způsobem zobrazení je tabulka s uvedením absolutních a relativních frekvencí pro jednotlivé položky (včetně možnosti zobrazení konfidenčních intervalů). | The default display is a table showing the absolute and relative frequencies for each item (including the option to display confidence intervals). |
| |
| Different kinds of information will appear by every [[en:pojmy:word|word]] (attribute) displayed in the frequency list of lemma //dřevo//. The basic information is located in the frequency column and displays absolute frequency of a given item in the searched concordance (if the concordance was altered in some way before the frequency list was submitted - e.g. with filters - the frequency list will be altered accordingly). V seznamu se zobrazí všechny položky s alespoň jednotkovým výskytem. Chceme-li výpis zúžit, můžeme nastavit **Minimální frekvenci** na hodnotu, která vyhovuje konkrétní situaci. | Different kinds of information will appear by every [[en:pojmy:word|word]] (attribute) displayed in the frequency list of lemma //dřevo//. The basic information is located in the frequency column and displays absolute frequency of a given item in the searched concordance (if the concordance was altered in some way before the frequency list was submitted -- e.g. with filters -- the frequency list will be altered accordingly). All items with at least one occurrence will be displayed in the list. If we want to narrow down the list, we can set **Minimum Frequency** to a value that suits the specific situation. |

| Vedle sloupce s absolutní frekvencí se objevuje i položka [[pojmy:ipm|i.p.m.]] Vyjadřuje **relativní četnost** zkoumaných jevů vzhledem k celkové velikosti korpusu. V našem případě se tvar //dřevem// objevuje v korpusu [[cnk:syn2020|SYN2020]] s absolutní četností 5 712, což představuje 46,89 výskytů na milion slov (i.p.m.). | The [[en:pojmy:ipm|i.p.m.]] column next to the absolute frequency column expresses the **relative frequency** of the studied phenomena relative to the total size of the corpus. In our case, the form //dřeva// appears in the corpus [[en:cnk:syn2020|SYN2020]] with an absolute frequency of 5,712, which represents 46.89 occurrences per million words (i.p.m.). |
| |
| Pro hodnoty absolutní i relativní frekvence lze pomocí další volby zobrazit i hodnoty **[[pojmy:konfidencni_intervaly|konfidenčních intervalů]]**, tj. rozsahy, v nichž by se dané frekvence (s pravděpodobností na určené **konfidenční hladině**) vyskytovaly v jiných, podobně sestavených korpusech srovnatelné velikosti. Konfidenční hladina je nastavena na 95 % a je možné ji uživatelsky změnit pomocí volby na 99 % nebo 90 %. | For both absolute and relative frequency values, an additional option can be used to display the values of **confidence intervals**, i.e. the ranges within which the given frequencies (with probability at a specified **confidence level**) would occur in other, similarly constructed corpora of comparable size. The confidence level is set at 95% and can be changed to 99% or 90%. |

| In the list to the left from the word, there are located links **p/n** which can be used for a quick display of positive or negative [[en:manualy:kontext:filtr|filter]]. By clicking on the **p** in the line displaying frequency for the word //dřevem//, we filter out this form from the current concordance,in the same way when **n** is activated, all of the occurrence of the given form will be eliminated from the current concordance. | In the list to the left from the word, there are located links **p/n** which can be used for a quick display of positive or negative [[en:manualy:kontext:filtr|filter]].

| After clicking on the heading of the column, the table will automatically be rearranged according to the selected column. This way it is possible to create a list that is arranged alphabetically (in addition to the usual list arranged according to the frequency). | After clicking on the heading of the column, the table will automatically be rearranged according to the selected column.

| Afterwards, it is necessary to select whether frequency distribution should be calculated regardless of the letter case. Selection of the option [[wp>Case_sensitivity|case-insensitive]] causes that all of the items are interpreted as having lower case, regardless of what type of case they actually have in the corpus. | Afterwards, it is necessary to select whether frequency distribution should be calculated regardless of the letter case.

| In case of custom settings of frequency distribution, we do not need to restrict ourselves to KWIC only (unlike when working with quick selection). It can be calculated from any context position to the right or left from the wanted word. The item //position// in the form enables us to select not only positions from the left (the preceding) context (6L-1L), but also KWIC itself and positions to the right (the following) context (1R-6R). The numbering of the positions (according to both current and older notation) is summed up in the following table: | In case of custom settings of frequency distribution, we do not need to restrict ourselves to KWIC only (unlike when working with quick selection).
