class Products extends \Magento\Framework\View\Element\Template
{ 
    protected $_registry;
    protected $_productCollectionFactory;
    protected $categoryFactory;
    protected $_productVisibility;
  
    public function __construct(
        \Magento\Framework\View\Element\Template\Context $context, 
        \Magento\Catalog\Model\ResourceModel\Product\CollectionFactory $productCollectionFactory,
        \Magento\Catalog\Model\CategoryFactory $categoryFactory,
        //\Magento\Catalog\Model\ResourceModel\CategoryFactory $categoryFactory,
        \Magento\Catalog\Model\Product\Visibility $productVisibility,
        array $data = []
    ) {
        $this->_registry = $registry;       
        $this->_productCollectionFactory = $productCollectionFactory; 
        $this->categoryFactory = $categoryFactory;
        $this->_productVisibility = $productVisibility; 
        parent::__construct($context, $data);
    }
    
    /*public function getCurrentCategory()
    {
        return $this->_registry->registry('current_category');
    }*/
    public function getCategory()
    {
        $category = $this->categoryFactory->create()->load()
                ->getProductCollection()->addAttributeToSelect('*')
                ->addAttributeToFilter('is_feature','1')->setPageSize(20)
                ->setOrder('position','asc');
        $category->setVisibility($this->catalogProductVisibility->getVisibleInCatalogIds());
        return $category;
    }
        
    /*public function getCategory($categoryId) 
    {
        $category = $this->_categoryFactory->create();
        $category->load($categoryId);
        return $category;
    }*/ 
    public function getProductCollection() {
        $collection = $this->_productCollectionFactory->create();
        $collection->addAttributeToSelect('*');
  
        // filter current website products
        $collection->addWebsiteFilter();
 
        // filter current store products
        $collection->addStoreFilter();
  
        // set visibility filter
        $collection->setVisibility($this->productVisibility->getVisibleInSiteIds());
  
        // fetching only 5 products
        $collection->setPageSize(5); 
        
        return $this->getCategory()->getProductCollection()->addAttributeToSelect('*');
        
        //return $collection;
        return $collection->getData();
    }
}

Path : app/code/Extra/Information/view/frontend/templates/myreview.phtml

<?php

    $objectManager = \Magento\Framework\App\ObjectManager::getInstance();
    $category = $objectManager->get('Magento\Framework\Registry')->registry('current_category');
    
    $productCollectionFactory = $objectManager->get('\Magento\Catalog\Model\ResourceModel\Product\CollectionFactory');
    $collection = $productCollectionFactory->create();
    $collection->addAttributeToSelect('*');
    
    $categoryFactory = $objectManager->get('Magento\Catalog\Model\CategoryFactory');
    
    $categoryId = $category->getId();
    $category = $this->categoryFactory->create()->load($categoryId);
    $collection = $this->_productCollectionFactory->create();
    $collection->addAttributeToSelect('*');
    $collection->addCategoryFilter($category);
    $collection->addAttributeToFilter('visibility', \Magento\Catalog\Model\Product\Visibility::VISIBILITY_BOTH);
    $collection->addAttributeToFilter('status',\Magento\Catalog\Model\Product\Attribute\Source\Status::STATUS_ENABLED);
    $ratingSummary = 0;
    $reviewCount = 0;
    $productCount = $collection->count();
    foreach($collection as $item){
       $ratingSummary = $ratingSummary + $item->getRatingSummary()->getRatingSummary();
       $reviewCount = $reviewCount + $item->getRatingSummary()->getReviewsCount();
    }

    $finalRatingSummary = $ratingSummary/$productCount;
    $finalReviewCount = $reviewCount/$productCount;

?>

Finally i call in Phtml file app/design/frontend/Codazon/fastest/bigmarket/Magento_Catalog/templates/category/products.phtml

<?php echo $this->getLayout()->createBlock("Magento\Framework\View\Element\Template")->setTemplate("Extra_Information::myreview.phtml")->toHtml() ?>

I get this kind of error 1 exception(s): Exception #0 (Exception): Notice: Undefined property: Magento\Framework\View\Element\Template::$categoryFactory in /chroot/home/a310743a/test.abc.com/html/vendor/magento/framework/View/TemplateEngine/Php.php on line 110

I think you have to get the Current category and get the product collection for that category, after that you can cicle the products and get the value that your intrested with, placing them maybe in temporary variables and then get those values and divide them for the numer of product of the collection, in that code it's missing the category where you want to load the collection,

    $categoryId = 'yourcategoryid';
    $category = $this->_categoryFactory->create()->load($categoryId);
    $collection = $this->_productCollectionFactory->create();
    $collection->addAttributeToSelect('*');
    $collection->addCategoryFilter($category);
    $collection->addAttributeToFilter('visibility', \Magento\Catalog\Model\Product\Visibility::VISIBILITY_BOTH);
    $collection->addAttributeToFilter('status',\Magento\Catalog\Model\Product\Attribute\Source\Status::STATUS_ENABLED);
    $ratingSummary = 0;
    $reviewCount = 0;
    $productCount = $collection->count();
    foreach($collection as $item){
       $ratingSummary = $ratingSummary + $item->getRatingSummary()->getRatingSummary();
       $reviewCount = $reviewCount + $item->getRatingSummary()->getReviewsCount();
    }

    $finalRatingSummary = $ratingSummary/$productCount;
    $finalReviewCount = $reviewCount/$productCount;

you can try something like this, starting from a category
