使用NCSS進(jìn)行分析

通過(guò)一些簡(jiǎn)單的步驟，您可以獲得有意義的數(shù)值結(jié)果和干凈清晰的圖形。使用“數(shù)據(jù)”窗口導(dǎo)入或輸入數(shù)據(jù)。打開NCSS程序進(jìn)行所需的分析，選擇列并運(yùn)行分析以獲得準(zhǔn)確且易于閱讀的數(shù)字輸出和圖形。

數(shù)據(jù)管理

NCSS可以輕松導(dǎo)入所有主要類型的數(shù)據(jù)文件，或者您可以復(fù)制和粘貼數(shù)據(jù)，也可以直接輸入數(shù)據(jù)。NCSS具有出色的過(guò)濾和轉(zhuǎn)換功能，可用于管理數(shù)據(jù)。

程序的選擇

使用下拉菜單，過(guò)程搜索或類別樹，可以輕松找到正確的分析或圖形過(guò)程。 可以點(diǎn)擊資源查看視頻，以了解如何在NCSS中選擇所需的過(guò)程。

分析設(shè)置

分析和圖形工具易于使用，并且每個(gè)選項(xiàng)都有內(nèi)置的幫助消息。選擇要分析的列，選擇所需的報(bào)告和圖，然后單擊“運(yùn)行”獲取結(jié)果。如果您需要其他幫助，則只需單擊一下即可獲得每個(gè)過(guò)程的完整文檔。

地塊設(shè)計(jì)

NCSS提供了80多個(gè)地塊。一些圖是常規(guī)分析過(guò)程（例如方差分析或回歸分析）的一部分，而其他圖則是獨(dú)立工具。所有NCSS地塊都是高度可定制的。用戶可以控制布局，符號(hào)，標(biāo)題，圖例，軸，網(wǎng)格線等。繪圖設(shè)置易于保存，以備將來(lái)使用或共享。

NCSS contains a comprehensive collection of statistical procedures for analyzing your data. These procedures cover a wide range of topics, including analysis of variance, clustering, correlation, curve fitting, cross tabulation, descriptive statistics, design of experiments, forecasting, time series, mass appraisal, meta-analysis, mixed models, multivariate analysis, nonparametric tests, operations research (linear programming), proportions, quality control, regression, survival, reliability, comparisons of means, and much more.

Plots, Charts, and Graphs in NCSS

NCSS has a large collection of tools for plots, charts, and graphs. These graphics procedures offer extensive flexibility to get your graph to look just as you want it, while still maintaining ease-of-use and intuitiveness.

NCSS Overview

The home window of NCSS is a column-based spreadsheet where your data can be easily entered or imported from all major statistical or data file types. Straightforward filters, transformations, labels, and formats can be used to get your data exactly as you want it to be.

Then you can choose from over 190 analysis and graphics procedures to analyze and visualize your data.

From a procedure window, you can select the columns you wish to analyze, adjust any other parameters to your liking, and press Run.

Your results will appear in an Output window that is prepared for viewing, printing, copying-and-pasting, or saving. A navigation pane allows you to quickly jump to any part of the output. You can double-click on a graph to save it in any of several file formats.

If you like a particular setup on a procedure window, and would like to perform the same or a similar analysis later, you can save the procedure template to be opened or shared at any time.
