Statistical significance considers the first and third of these concerns. The middle one, bias, cannot be detected by mathematical deductive logic: it needs detailed information on the way the sample was chosen. This is dealt with in the notes on bias.
A HEIC file is a raster image saved in the High Efficiency Image Format (HEIF), a lossy compressed format. It may contain still images, image collections, image bursts, or image sequences, along with metadata that describes each image. HEIC files may also appear as .HEIF files.
Essentially, there are lots of benefits of using HEIF, even if it is a bit confusing that the file is called HEIC rather than HEIF on Apple devices. Hereâs why HEIC files are great: Around half the size of JPG for the same quality; Can store multiple photos in one file (ideal for Live Photos and bursts) Supports transparency like GIF files
