#روایی_ظاهری و #محتوا از جمله فرایندهای لازم در #اکتشاف_پرسشنامه از طریق #رویکرد_کیفی است که قرار است به #رویکرد_کمی تبدیل شود. یعنی #رویکرد_آمیخته.
پس از انجام روایی ظاهری( ویرایش ادبی، مفهوم ) سوالات و همچنین روایی محتوا ( شاخص های CVR و CVI) می بایست پایایی کدهای تبدیل شده به سوال در نرم افزار های کیفی ( مکس کیو دی ای، اطلس و ان وی وو) توسط #آزمون_گاتمن از سوالاتی که در اختیار نمونه تحقیق قرار گرفته پایایی گرفته شود. این فرایند ( آزمون گاتمن) در نرم افزار SPSS انجام می شود.
این آزمون بر اساس کیس ها ( ردیف ها ) پایایی را می سنجد. این آزمون ردیف ها، یا کیس هایی را که داده های آنها شبیه به هم هستند را در یک دسته قرار میدهد.
کاری که این ازمون میکند این است که کیس ها را بر اساس تجانس و همگن بودن جواب هایشان دسته بندی میکند.
در این آزمون، #نرم افزار برای هر دسته ضریبی به نام #لامبدا را محاسبه میکند. کوچکترین لامبدا در بین دسته های ارائه شده باید بالای ۰/۶ باشد. تا ادعا کنیم پرسشنامه ای که ساخته ایم و هنوز متغیر ندارد #پایایی دارد.
🔹دستور آزمون گاتمن در اس پی اس اس:

Telegram Q&A

Q: How does hottg.com work?

Once you've set up a username, you can give people a hottg.com/username link. Opening that link on their phone will automatically fire up their Telegram app and open a chat with you. You can share username links with friends, write them on business cards or put them up on your website.This way people can contact you on Telegram without knowing your phone number.

With Telegram, you can send messages, photos, videos and files of any type (doc, zip, mp3, etc), as well as create groups for up to 200,000 people or channels for broadcasting to unlimited audiences. You can write to your phone contacts and find people by their usernames. As a result, Telegram is like SMS and email combined — and can take care of all your personal or business messaging needs. In addition to this, we support end-to-end encrypted voice calls.

Q: What is Telegram? What do I do here?

Telegram is a messaging app with a focus on speed and security, it’s super-fast, simple and free. You can use Telegram on all your devices at the same time — your messages sync seamlessly across any number of your phones, tablets or computers.

Q: Who is Telegram for?

Telegram is for everyone who wants fast and reliable messaging and calls. Business users and small teams may like the large groups, usernames, desktop apps and powerful file sharing options. You can appoint admins with advanced tools to help these communities prosper in peace. Public groups can be joined by anyone and are powerful platforms for discussions and collecting feedback.In case you're more into pictures, Telegram has animated gif search, a state of the art photo editor, and an open sticker platform (find some cool stickers here or here). What's more, there is no need to worry about disk space on your device. With Telegram's cloud support and cache management options, Telegram can take up nearly zero space on your phone.

Q: How is Telegram different from WhatsApp?

Unlike WhatsApp, Telegram is a cloud-based messenger with seamless sync. As a result, you can access your messages from several devices at once, including tablets and computers, and share an unlimited number of photos, videos and files (doc, zip, mp3, etc.) of up to 2 GB each. And if you don't want to store all that data on your device, you can always keep it in the cloud.Thanks to our multi-data center infrastructure and encryption, Telegram is faster and way more secure. On top of that, Telegram is free and will stay free — no ads, no subscription fees, forever.

Q: Can I make calls via Telegram?

Yes! Voice calls are currently available to users around the world.
